Consumer Redressal

I purchased a product from SNAPDEAL on EMI and they have confirmed that there is an EMI facility available. When I got my credit card bill, the EMI was not converted. I spoke to bank and they said the EMI option is available in selected merchants and they have not received any request from SNAPDEAL. I spoke to SNAPDEAL they says your bank is not converted. I been harassed by SNAPDEAL the customer service agents/managers/supervisor are so rude they don\'t even respect. I have even escalated the issue to CEO Mr. Kunal, however he doesn\'t even care about customer issues. If I don\'t pay the credit card bill they will charge me interest and will effect my CIBIL rating. I have been mentally torched by snapdeal, because of this stress if some thing happens to my health SNAPDEAL is responsible. Please help me in this issue.
