HSBC — Credit Card Bill

I have one HSBC spencers gold credit card, initially I used this card for several purchasing but after using one month I never received the bill. I made several complains and finally got a old bill with addition of several penalty charges for late payment. I paid once and thought things will be fine, but not, it's their tendency to send bill with one month late just to charge huge penalty. I have alrdy stopped using the card but the old bill amount, which I still yet to recv. I tried customer care several times but no result. I will suggest everyone not to go for any HSBC product, they are defaulting with the customers. The most irretating thing is that, once ur bill is generated, u will start recving so many miss calls in ur mobile from HSBC cust care, approx 15 miss calls per day, when I call back they said this are automated calls. I have used credit cards for many banks, but HSBC has the wrost service out of all.
