Incorrect order not being collected as promised!!!!!!!

On the 8th of Aug I placed an order after I had struggled to do so because of my account being blocked because of an attempted ********** purchase in March. On the 13th I received 2 parcels the 1st being a partial order as 1 item was out of stock and the 2nd was an item that I did not order at all. On the 13th I sent an sms to their "return" number and I followed up with a call on the same day and I was told that a pick up would be arranged. I sent various mails in the days following the call and got no response. On the 24th I called again to enquire how exactly I ended with an item I did not order and I was told I had ordered the item in March and that there was no stock, my issue with this is had I not placed an order and changed my address to the correct one, this order would have been delivered to the ********* who "attempted" to use my account. But if the order was cancelled then how was it delivered? I was given a reference number on the 24th of August as well as assurance that the item will be collected in 7 days. When the 7 days passed, I sent e-mails again to follow up and 11 days ago got a response from N. Har**** to say the item will be collected within 7 days.

I am getting sick and tired of this back and forth and e-mails that go unanswered. Can you please collect this item as it is taking up space in my house.

The service being rendered is absolutely shocking!
