HDFC Bank — hdfc credit card and one assist fraud

I had been duped by an hdfc executives into purchasing one assist for one year to have an enhanced credit limit. It was month of september when i got this call. I was told that rs. 1899 shall be deducted from my credit limit and the same shall be refunded the next month. However, when i got my following month's bill the amount was not refunded. I called the customer care many a times. Everybody gave their versions. Some said they are taking a complain and the amount shall get reimbursed soon, others said we don't have such policy itself. I was also not provided a complaint number for the first two times i called. And when i was provided a complain number i never got a resolution for same. Then i started getting calls from oneassist. I narrated them the entire thing again. So they canceled my membership but refunded me only rs. 949.50 in december. They told me to talk to hdfc for the rest of the amount because it was them who had promised for a full refund. I have called hdfc customer care again and even spoke to a senior floor person but he tried to make fool of me. He even asked me to recall the names of persons the persons i spoke to at hdfc. This is the worst level of service.
