Account closed but I'm getting charged

Absa blocked my account, after I wrote a review here they actually called back and allowed me to take my money out and told me to not use the account again and not deposit any money on the account and I did exactly that.

For the past month I have been receiving threatening Sms's from Absa about my account being on a negative and that I will get handed over if I don't do a deposit in the account.

I am now very confused because Nqobile from ***** department told me not to do any deposits on the account. When I emailed the said Nqobile and sent the Sms's as well she simple ignored my emails meanwhile interests are accumulating in an account that I was told not to use. Surely I can not be responsible for this.
