Closed account still active

Good day

I went to Edgars Mall@Reds on 29 December 2020.

I asked for the final figure to close the account and they told me it was R339. I paid the amount and had to wait for more than an hour for them to close my account on a certain computer. The other computers could apparently not close the account.

They took my card and cut it up and ensured me that the account is closed.

I have received calls and SMS since then for an amount outstanding.

I have told the people that the account is closed and asked them to please stop harassing me.

They now handed the account over for legal action.

I tried calling Edgars Head office 16 times today and the line just cuts off.

How must I solve this if nobody is available.

The legal department just puts me through to Edgars Head office and again the line just cuts off.

Please help to solve this once and for all.
