HSBC Credit Card Division — Forcefully charging Mediclaim policy without my consent

I have subscribed to Tata AIG Policy no BTHC[protected] & BTHC[protected] which i reqested to cancell the policy over phone to HSBC helpline nos. as i tried several times to Tata Aig but there lines remained busy. But to my surprise i found the prmium charged in my last bill due on 15th March,10. I have given several mails to cancell as well as spoke over phone to HSBC helpline and they confirmed that they will respond back within 2 working days, but no one is responding. There is also mail several times that they will respond within 2 working days but no one is responding.

Pl lodge my complaint and take strict action with such banks so that customers are not harrased again and again. There may be list of long such cases with you, but how you still allow such banks to run this unfair means of business. Kindly solve the issue at the earliest.
