Need a refund and a interest for 1.5 months and penalty for the time which they have taken to resolve the issue. I have spent more than 15hours for this issue by calling them multiple time and emailing them. But still no refund.

I am not able to attach anything as of now here. But we have all the proofs and we have been mailing them and doing everything we can, but no response
