On 6-7 -2020 I ordered on non stop wears for a combo deal of night suits. On 10-7-202 I receive a package o[censored]nstitched cloth. On calling this no.-
‭[protected]‬- a person named Deepak replies he agrees that a wrong delivery has been done, on asking for refund he says a message will be sent you fill the form and you will receive refund. As I don’t receive any message he asked me my debit card number on refusal he asked me to download airdroid app . For refund. When I continuously told him to do Paytm he refused. I said usually companies do refund on same debit card number then what’s the problem. He said no things like this also can be done. While not complying to his instructions he was rude and his language was not uptomark.
