Error when setting values from JSON on my UITableViewCell

I have a problem when set values on my UITableViewCell. I get this data from Web Service in JSON format, to do this created a class that contains all the data from JSON.

That is the Class.

Refunds.h

#import <Foundation/Foundation.h>

 @interface Refunds : NSObject

 -(id)initWithJSONData:(NSDictionary*)data;

 @property (assign) NSNumber *refunds_id;
 @property (assign) NSNumber *request_number;
 @property (strong) NSString *policy_code;
 @property (strong) NSString *company;

 @end

Refunds.m

#import "Refunds.h"

 @implementation Refunds 

 @synthesize refunds_id;
 @synthesize request_number;
 @synthesize policy_code;
 @synthesize company;
 -(id)initWithJSONData:(NSArray*)data{
 self = [super init];
 if(self){
    NSLog(@"initWithJSONData method called ");

    //NSString *u = [data valueForKey:@"policy_code"];
    //NSLog(@"%@",u);

    refunds_id =  [data valueForKey:@"id"];
    request_number = [data valueForKey:@"request_number"];
    policy_code = [data valueForKey:@"policy_code"];
    company = [data valueForKey:@"company"];
    }
    return self;
    }
    @end

In the ViewController where I use the UITableVIew I have this implementation

NSMutableArray refunds_view = [[NSMutableArray alloc] init];

for (NSDictionary *each_refunds in self.list) {
    Refunds *refunds = [[Refunds alloc] initWithJSONData:each_refunds];
    [refunds_view addObject:refunds];
}

In the method

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{}

I have this:

Refunds *current = [refunds_view objectAtIndex:indexPath.row];
cell.date_admission.text = [current company];

In the line cell.date_admission.text = [current company]; gives me the following error

-[__NSArrayI length]: unrecognized selector sent to instance 0x8bc4eb0
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayI length]: unrecognized selector sent to instance 0x8bc4eb0'

That is the JSON Format.

[
{
    "id": 1,
    "holder_rut": 12345678,
    "holder_name": "Otro Pedro",
    "rut": 12345678,
    "name": "Otro Pedro",
    "refunds_view": [
        {
            "id": 60,
            "request_number": 456789,
            "policy_code": "3500009001",
            "company": "Benefits",
            "beneficiary_id": 1,
            "concept": "Prueba More",
            "date": "2014-05-21",
            "amount": 20000,
            "deductible_amount": 0,
            "max_applied": 0,
            "yearly_balance": 97,
            "payment_amount": 14000,
            "payment_method": "Deposito",
            "bank": "Estado",
            "account_number": "1234567",
            "payment_date": "2014-06-20",
            "created_at": "2014-06-18 21:55:41"
        }
    ]
}

The data I need to show is that this refunds_view

View Controller Code

//UITableView Methods Implemented
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

static NSString *simpleTableIdentifier = @"SimpleCell";

RowCell *cell = (RowCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

if (cell == nil) {

    //inicilitacion cell custom
    cell = [[RowCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}


Refunds *current = [refunds_view objectAtIndex:indexPath.row];
NSLog(@"company %@",[current company]);
cell.date_admission.text = [current company];


return cell;
}

ViewDidLoad

 - (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.

//Geting data from JSON Refunds
SBJsonWriter *jsonWriter = [[SBJsonWriter alloc] init];
NSDictionary *dict = [NSDictionary
                      dictionaryWithObjects:[NSArray arrayWithObjects:rut_user, nil]
                      forKeys:[NSArray arrayWithObjects:@"rut", nil]];
NSData *jsonData = [jsonWriter dataWithObject:dict];

//URL
NSURL *url = [NSURL URLWithString:@"URL"];


NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
//[request setURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:token forHTTPHeaderField:@"X-Auth-Token"];//TOKEN
[request setValue:[NSString stringWithFormat:@"%d", [jsonData length]] forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody: jsonData];

NSError *error = [[NSError alloc] init];
NSHTTPURLResponse *response = nil;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

NSLog(@"Response code: %d", [response statusCode]);
NSString *responseData = [[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];

SBJsonParser *jsonParser = [SBJsonParser new];
NSDictionary *jsonResponse = (NSDictionary *) [jsonParser objectWithString:responseData error:nil];//I'm a Json Refunds


self.list = [jsonResponse valueForKey:@"refunds_view"];
NSLog(@"Quantity of Refunds Founds %i",[self.list count]);

refunds_view = [[NSMutableArray alloc] init];


for (NSDictionary *each_refunds in self.list) {
    //NSLog(@"each_refound %@",each_refunds);
    Refunds *refunds = [[Refunds alloc] initWithJSONData:each_refunds];
    [refunds_view addObject:refunds];
}   
}

I need Fix it ASAP. Thanks. Best Regards.
