HSBC credit card customer service is worst service. Review on HSBC Visa Credit Card

I am having HSBC credit card. I want to redeem my bonus point from Jan'09, regarding this I called up to their Customer Care 20-25 times. After logging request first time, I was waiting for the product delivery but not received the product after 21 days. After that I again called up to their customer care , they told me that your address was not correct, but for address change I already logged the request on Sept-Oct '08, I again logged the request for address change, after that reward point redeem, but nothing happen. I called up again on April'09 for this they told me that your card is not active.

So I again logged the request for activation of my card on April, in the first week of May I called up again for redeem my bonus point, before logging the request I just confirmed tha my card is in active state or not, they told me that it is in active state. After that I logged the request for product. On the same day I called up again for just confirming that my request logged porperly or not, you know that I again shocked that their executive told me that your card is not in active state, and they given me some number to activate my credit card. So, friends let me know have you ever seen these type of service from any international bank. I think it is the worst bank in the world.
