Hi,

I want to close my credit card, but their all numbers, helpline numbers, complaint email id, nothing is working. They are regularly living interest on my account. I am helpless as there is no point of contact to close my account. Even their branch people which is near my location says, they don't handle the account closure. When asked about how to do, they give those same numbers which are not at all reachable. Please help me out how to close my credit card account.
