Very poor service

On 30 January I ordered an electric mixer from the @home online store. The cost of the item was R10 000-00. I paid R4990-00 cash and put the balance on my account. They advised that they will let me know where and when to collect the item. 2 days later I received a sms that I can collect my new mixer from the branch at Willowbridge. When I got there and opened the box with the store attendant the item inside was not what I have ordered. The invoice was for the correct item but it was not sent to me. I then sent an email to the query department explaining my irritation and asked for my money back because of the wrong item. The next day I recieved a reply with not even a slight apology for the poor service explaining that I need to go back to the store for a credit. I then went back to the store only to be told that they can not refund me in store because they can not credit an item that is not in their stock. This was the only thing that made sense to me. The shop attendant then phoned the online department and explained the situation to them. They then said that they need the item back before they can do the refund for the full ammount onto my account. This suited me because I still want the correct product. It has now been more then a week and the wrong item is still not even collected from the store. This is unacceptable as @home is already earning interest in their account with my money while charging me interest on my account for an appliance that I don't even have. I really hope this message reaches the necesary people to sort this out and deliver the correct item. Up to date only the ladies in store apologized for the poor service that wasn't even their mistake in the first place. I doubt if I will ever do business with @home in the future. It seems that once they had my money they do not care if I recieve my product or not.
