Hello sir
My debit card is 3384 and my account number 6374. I had an amazon refund of ₹ 537 as it was supposed to reflect in my account by 27th november but it did not happen, then i contacted amazon, then they send me reference no (# 1ukiqdn80000k1rngb5o). And then i contact your customer care and i gave them all the details, also told the reference number, but your customer care boy did not have any help, and they said that there is no problem from the bank's site. Sir please check and add my amount
