HDFC Bank — hdfc prepaid gift card

Hello,

I purchased a card for rs. 6500 for a colleague as a farewell gift. My colleague, however, has not received it. It was supposed to be delivered by 23rd june, 2020. It is now the 1st of july. I have tried reaching out to hdfc multiple times, but no response from on email or via call. About 6 o[censored]s put in this money to say goodbye to our friend who is in dire need of this amount. Please help us.
