Payzapp — failed transaction : money did not refunded

Address: Khordha, Odisha, 751003

I have made a transaction at reliance fresh bhubaneswar using payzapp bharat qr application of hdfc bank. Transaction shows time out at retail store. But at payzapp it shows successful and payzapp deducted money from my sbi irctc credit card. Money has not been refunded yet. Date of transaction 29.10.2017. Amount is rs. 926.61.

I have written email to payzapp and even try to contact then at their toll free no. But they are not responding.

Please take action. This is fraud.
