HSBC Credit Card — account closed still getting credit card statement showing more than 2300 RS amount due

Address:

Pune, Maharashtra

Hi,
I had a HSBC credit card. on June 23rd i got mail + call from HSBC that they are closing my credit card account because of some company policies.
After that at month end i got Card statement with annual fee for this year.
When i called customer care and asked about it he said he is reverting charged amount.
But this month i got new credit card statement with annual fee + late payment charges !
Now when i again called customer cars he said your charges are already reverted but statement was generated before that.
But hen i asked for a mail for confirmation. He said he can’t do that.

Every time they saying my account is closed but still why i am getting credit card statement with some amount due?
Also the last statement (one which got after account closed) was sent to me by POST and not via e-mail! (All statements were sent by e-mail before)
