Hypercity — multiple payments for one transaction

Address:

308/B, Sainath CHS, P.G Marg, Malad West, Mumbai 400064, 400064

Hi,

I would like to register a complaint against hyper city malad west as i haven't yet received a refund for the multiple transactions that occurred for a transaction of 1st of december.
I had paid through upi which went through successfully, but i was asked to pay again as it didn't reflect at the counter.
I was assured that if there was a multiple payment it would certainly be reversed.
Hence, i used my credit card for the same.
The transaction went through twice and the payment has not been refunded although i was in touch with one of the supervisors since 2nd december and have sent him all the requested details on whatsapp.

Please help me with the same. This is a bad shopping experience with hyper city.

Thanks
Ketan
