Homechoice *****ing a closed account

I was a customer for homechoice but closed my account early 2017. June 2018 I received a statement saying I had made a purchase worth R4000, which I never did. The statement had my correct ID number and phone number but wrong address from another town. I called and emailed to correct this wrongful purchase but I wasn't helped instead more statements have been coming. I have always known when you purchase from HC the agents call you and confirm details but I never received a call concerning the so called purchase. This is frustrating because clearly someone is responsible for this but no one from HC cares to correct this mistake. As I am in Swaziland I receive my goods from the post office by signing for them before receiving them with my ID which in this case never happened since my ID is with me and has never been ****** . I closed my account and stated that I wanted nothing to do with the company, they told me if I close it I would start afresh the process of becoming a customer if I decided to buy from them again of which I agreed. Now I have made a purchase but I never gave my payslip or ID to reopen the account. This is sick and frustrating.
