HSBC Platinum Credit Card — Account closed without information

Address:

Bangalore, Karnataka

In past month i tried to make swipe with my platinum credit card no.[protected] but they were dishonored.Which was very embarrassing. There was no formal notice from bank(HSBC's) side if they had put my card on hold. I tried their customer care several times but the call always ends before their executive is there on line. This has repeated for about 4-5 times.
After i launched a complained through email they informed that my account has been closed by bank on 18 august 2010. Further i asked about my loyalty points they told that they can't redeem them now. First of all they have closed my account without informing to me i have already enrolled for "e statements" but still they were least bothered to sent even a mail to inform about closure of my account and secondly how can they tell me that now i can't redeem my loyalty points.
I need a proper reply and if possible again my card should be activated along with the loyalty points where they closed it.
