I have a credit card with HDFC but I have been paying up my dues on time so no much late charges and penalty over a 4 year period though I can remember a couple of times when it has been done. But my biggest problem is when they lock a certain % of my limit and dont allow me to use it. I was put in a bad spot of bother because as the call centre guy said there was a "hold on my funds" even though I was ~ 30K from completing my limit. It was a desperate situation in a hotel and I had to catch my flight back home. If I had known this ombudsman I would have surely taken up this matter !!
