HSBC Credit Card Department — employees does not know how to behave with customer and only doing false promise

one thing is dead sure that you people are not customer oriented and your employee(Kala and sweta from mumbai,[protected] and some more on bangalore they don't know how to speak and how to solve the query eventhough they are working for customer service.
I had been given :these many numbers, but answer is and still i am not clear what to do : some numbers are not working and some numbers there is no answer and some numbers even the custimer is calling 100 times they are simply cutting the line as if they are playing and we are full by taking the card:
I have closed the card due to inconvenience and falsa bills and promise and i sufferd a lot:
My account got settled for 42310 rupees in 3 installments :I paid 2 check of 30000 and i have to pay 12310, the check got bounce, so can you please tell me being a gentelman, how much amount i need to pay if the check got bounce.
And please in future tell your employee to behave like a gentleman and teach them how to behave with customres: otherwise after lehaman next will be HSBC and it would not be any surprise for us:

Thanks,
Sushant
