Google India / Tez — Google Adwords account suspended and balance not refunded

I had a Google adwords account[protected] and they suspended my account stating that I violated their policies. I had an outstanding balance of Rs760 and I cancelled my account to receive the refund. Later I received a notification that Google is not able to refund the money back to my card and please remove the existing card and add a new card. I did as per their guidelines and then I waited for long and Google is saying that they are not able to verify if the payment was successfully captured or not.
I don't know what is wrong with Google Ads. But I've been scammed by Google since an year now and I need my money back
My email id is [protected]@gmail.com
I have been doing the account cancellation every month to see if I get my refund and Google customer assistant people don't even know what is wrong with it.
