HSBC Credit Card — Constant harrassment by HSBC on false charges incurred on my card by someone else

Hi,

My name is Prarthana Chatterjee.
I was issued a HSBC gold card. However, I lost it sometime in March-April 2005. I had called up the customer care and requested for a card deactivation. The customer care had confirmed that my card has been deactivated. Subsequently, after some days, I got a call from the customer care stating that a payment of 786 is due on my card and that I need to make this payment before my card can be deactivated. I made the payment via cheque( have proof in this regard) in my bank statement. I again requested the customer care to ensure that the card is deactivated. They confirmed that this has been done. I did not receive any statements after that. However, it seems that the bank never deactivated my card and my card was grossly misused by someone.
Almost after a year, sometime around July 2006, the HSBC bank collections team started calling and threatening my family stating that I had run away with around 32000 of the bank's money. They verbally abused my family over the phone. I then spoke to the bank stating that I had lost my card and had also requested the bank on many ocassions to deactivate my card. Also, I requested for proof in this regard that I had incurred 32000 worth of expenses on my card. The bank refused to provide any proof and continued to threaten me and my family. My family also lodged a complaint in the Lalpur Police Station in ranchi against Mr. Kiran Bopaiah from HSBC who had been calling, threatening and abusing my family and me.I had also sent a written complaint in Aug2006 to the Head- Card operations who was based out of Mumbai.
On 17th May 2007, I was informed by HSBC via email that my card was deactivated on 3rd Jan06, whereas I had placed the request for deactivation in March-April 05. During this period, my card was grossly misused to the tune of around Rs. 30000.
Now, I am being asked by HSBC to make a payment of 74000 including interest charges for this amount. They have refused to furnish any proof that I had incurred any of this expenditure or the fact that that I had called up customer care multiple times to request my card deactivation.They have deleted all the call records in my name and stated that I had never made any calls.
They are continuing to threaten me and my family stating that they have issued warrants in my name.
I am being asked to pay a large amount of money on the card which has been incurred by someone else.I had also done all the needful to get my card deactivated on multiple ocassions.However due to sheer negligence of HSBC to do the needful, I am being made to suffer.
I therefore seek your help in getting this case resolved.

Thanks,
Prarthana Chatterjee
