HDFC Bank — transaction failed but cash not refunded

Address: Ernakulam, Kerala, 682316

I transfered rs 22000 from my sbi debit card to payzapp but cash not loaded. Then i called customer care service of hdfc, but they said that the transaction failed and amount was already debited from my sbi account. And i got a message from sbi that "thank you for using your sbi debit card 459xx6188 for a purchase worth rs22000.0 on pos 297692*213328 at payzapp wallet load txn# 7304*04243." but it's already 5 days crossed. No respond from hdfc. Why the customer care service not active for this types of major issue.
