********** activities using my account

I have been a customer at HomeChoice for years but now I want to have my account closed. I found out that there was an order done in my account of more than R22 000 which I did not place. The item was delived, according to their online tracking system. I received an sms confirm a packed item which I dont know anything about and immediately I called their call centre to alert them of this and sent an email as well. The responce to the email was that they will have the item returned to their warehouse. Few days later another sms was received confirming that the item was delivered. I called the call centre and sent another email. But nothing is being done. I was asked to send an affidavit explaing that I did not order anything. The email I'm suppose to send this affidavit is blocking my emails.

This is painful because I have tried numerous times to alert HomeChoice of this ***** in my account and they are ignoring me. I have been sorting my finances and trying to avoid debts because I cannot afford anymore debts. My financial reaponsibilities are too much at this point. And I want to keep my credit score good and this thing happens. I dont have any money to pay them. I am so stressed now
