[Resolved]  State Bank of India — Absurd renewal charges & phone calls

I am a doctor and i was forcefully given a free SBI credit for one year in 2004 whch was called as doctor's card, i hardly used it and at the end of the term duly informed them that i dont need it any further. I recieved a letter from them saying that there is nothing outstanding and they will be happy to have me as a customer later on. All of a sudden after 4 years i started receiving rudecalls, sms and letters saying that over 12000 is due and i can settle by paying 2300. I think this is extortion of the third rate by a reputed bank!
Phoen calls were from [protected]
Please rectify. i see similar complaints in this forum and i believe strict penalty should be imposed on such agencies to redress the consumer grievances.
