HDFC Bank — Refund of Amount in Card

Address:

Chandigarh, Chandigarh

I have been charged late fees on my card and my card blocked unnecessary.

Details Below:

1. Card charged with Rs. 44067 on Jan 1
2. I write a mail to HDFC and get a response the refund will be processed and no charges will be applied.
3. Also, assured no charges will be levied and also no need to make any payment
4. I pay rest of the balance and assume this is closed
5. Next Payment cycle I was charged 700 for late fees though the entire amount was credited back by 31 Dec as refund was processed by that date
6. Customer service told it is a mistake and they will refund but asked my to pay advance charges for next cycle to unblock card
7. I write 3-4 mails to grievance cell but no response

Is this how a 10 year old relationship is being treated.
