Firebase node deletion not working Android

I have a for loop of dataSnaphots like this:

for (final DataSnapshot advertiser : dataSnapshot.getChildren()) {

and I have a button called 'delete' which has to delete a node in my database (code placed inside the for loop)

delete.setOnClickListener(new View.OnClickListener() {
                            @Override
                            public void onClick(View v) {
                                new AlertDialog.Builder(getActivity())
                                        .setTitle("Delete service")
                                        .setMessage("Do you want to delete this service?")
                                        .setIcon(android.R.drawable.ic_dialog_alert)
                                        .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
                                            @Override
                                            public void onClick(DialogInterface dialog, int which) {
                                                databaseReference.child(advertiser.getKey()).removeValue()
                                                        .addOnSuccessListener(new OnSuccessListener<Void>() {
                                                            ProgressDialog progressDialog = ProgressDialog.show(getActivity(), "", "Deleting service...", true);
                                                            @Override
                                                            public void onSuccess(Void aVoid) {
                                                                progressDialog.dismiss();
                                                                Toast.makeText(getActivity(), "Service deleted", Toast.LENGTH_LONG).show();
                                                            }
                                                        });
                                            }
                                        }).setNegativeButton(android.R.string.no, null).show();
                            }
                        });

the toast to confirm the deletion is appearing but the node still remains in my database

If you declare databaseReference as FirebaseDatabase.getInstance().getReference(), then it will point to root data of your database. And from your code, I see:

databaseReference.child(advertiser.getKey()).removeValue();

That will remove value on your-database-root/(advertiserkey). But from your database structure screenshot, I realize you want to delete data on your-database-root\Advertiser\(advertiserkey). So your code should look like this:

databaseReference.child("Advertiser").child(advertiser.getKey()).removeValue();

And that should do
