Poor customer service

Hi my name is Julia Mazibuko I have an account with Homechoice and I am not happy with the service I got from Homechoice. Last month I bought blankets and appliance pack, I had to cancel the appliance pack because it's not what I wanted, the courier came and collected the appliance 1st week of April if I'm not mistaken. Now I'm surprised to see tht they have debited installment that included the appliance pack that was collected and taken back to Homechoice. I called customer care and the lady told me that Homechoice have not received the appliance pack, I mean that is not my problem as a client because the item was collected from me. I need Homechoice to cancel the appliance pack immediately and refund the difference.
