I thought as my blog doesn't gather much traffic , I can write my personal useful stuff here as well, it may be helpful to someone.
I had some issues with my HDFC credit card and I wanted to talk with the real customer care personal , but it's not easy to find the way for this.
So, here are the steps :
1) use this link to find your customer care number try to call from registered number:
HDFC Bank Customer Care Number - Call Our 24x7 available Customer Care Numbers across India
2) for credit card dial 2
3) for credit card balance , payment and statement information dial 1
4) last 4 digit followed by # key.
5) credit card number with # key
6) validate with your pin dial 1
7) thank you, your credit card is validated
8) it will say your credit card limit
9) dial 2 for last 10 unbilled transaction.
10) complaint for card dial 4.
at this point you will be connected to customer care executive , also they reply of tweeter , so you can try that as well. @HDFCBank_Cares.
