How can I know that user just renewed a google play subscription?

I'm working with google play subscription and couldn't figure out how to know when user renewed the plan for one more period. I'm giving 3 credit's to use one feature of my app, and each month the user would receive 3 more credit's if renewed the subscription.
I'm monitoring the user plan using this method below, but it caches the user subscription for a while, so I'm afraid of giving the user 3 more credits when he actually did not renewed the subscription. 

fun queryPurchases() {
    val purchasesResult = mBillingClient?.queryPurchases(BillingClient.SkuType.SUBS)
    if (mBillingClient?.isFeatureSupported(BillingClient.FeatureType.SUBSCRIPTIONS)?.responseCode ==  BillingClient.BillingResponseCode.OK) {
        if (purchasesResult?.responseCode == BillingClient.BillingResponseCode.OK) {
            purchasesResult.purchasesList?.addAll(
                    purchasesResult.purchasesList)
        }
    }

    if (purchasesResult != null && purchasesResult.purchasesList != null) {
        if (purchasesResult.purchasesList.isEmpty()){
            purchasedPlan.postValue(null)
        }else {
            purchasedPlan.postValue(purchasesResult.purchasesList[0])
        }
    }
}

How can i handle this situation properly? I thought about giving the user 3 credits anyway on the following month and remove 3 credits if suddenly the plan turns out a free plan, but I think this approach would be very abusable

To get the most recent information about subscriptions you can use queryPurchaseHistoryAsync() instead of queryPurchases(). You can combine it with your local caching algorithm to reduce abuse level. Link to documentation

Warning: queryPurchaseHistoryAsync() makes a network call, which could result in a charge to the app user.
