Zebpay — paid rs 10,000 but its not reflected in zebpay app

I made a payment of Rs 10, 000 on 10th december 2017. its not reflected in zebpay app. i can see Rs 0 in rs deposit in app. i have my bank statement that payment has been credited to zebpay. i filed tickets on zebpay support. their response is very late and after few days that ticket was closed. I tried their toll free customer support number but they know hindi and do not know english.
