Order id[protected]w

I have contacted the customer care, they replied, we don't know about the store credit, hence ask me to send the mail to [protected]@jiomart.com.

Continuous 5 days, they replied, refund has initiated, check your bank side.

I will reply, it is store credit payment, can you check on it.

Continous 5 days, they replied the same and stop replying.

Can anyone help me, how to contact them?
