treated unfair by Foschini group company

I have an account with Foschini Group store which is Markham. I settled my account last year November 2018, called the customer contacts center for account closure on that same day . when I come back from maternity leave I got emails informing me that my TFG account was due for an amount of R253 that was April 2018. I called and enquired about that they said its as a magazine subscription which was not closed, so I have pay that amount in order for to close my account. I paid that amount on the 25th of August 2018 now they saying my account is handed over and they are unable to close my now they will close it on the 12 of September 2018, Which I don't trust It will happen, called multiple time this month even requested to speak to their team leader, he said he will get back to me on Monday the 3rd September 2018 after 20mines and didn't. Nomsa Nayasa was the lady I speak to on Monday the 27th of August 2018 ( ********** 576)
