HDFC Bank — my money cut from credit card but not added to payzapp wallet

I tried transferring 5k from my credit card to my payzapp account, the transaction was unsuccessful. Then again i did a transaction fro another 5k, it failed again. 10k has been cut from my credit card but nothing reached my payzapp wallet. I tried calling payzapp customer care but no response from them. Please let me know when i can get my money back.
