The following email was sent to an internal mailing list in my organization. I think it is worth reproducing it here.
If you are holding an HDFC Value plus credit card and have in past few months seen something like an excess cashback billed to your card , please get in touch with HDFC customer care people asap .
I too had experienced the same in 2 of my past months card statements .Infact my roommate and some of my friends were also charged for the same thing .We talked to thee HDFC people and finally after putting in some efforts were successful to get our money back.
To add to that I had personally asked them to send me an apology letter for the same , which , though I got is in a very sugar coated language,but nevertheless I got my money back..I told them that I have a number of friends who were confronted with the same issue , so they gave me a POC for this issue whereby if anybody among you has come across the similar problem ,you can talk to this POC and he'll get your problem resolved .
The POC is : Sai Rupendra.. (U can call HDFC customer care and ask the person taking the call to directly connect you to Sai Rupendera).
So folks , please utilise the services of this person to claim back your hard earned money from HDFC .
Do examine your credit card statements carefully. You should not allow yourself to be charged for something that you did not spend!
