Receiving the wrong order from homechoices.

I am not happy about Homechoice, i have been a loyal customer to them but they treat me unfair i have receive a wrong order two times, when i tell them to come and collect it they told me that i must take the item to the showroom knowing that in Mpumalanga province we dont have homechoice showroom. So which mean i have to pay for somethimg that i won't be able to use. When its comes for delivery they make it quick but collecting is an issue. I have called and send emails to notify them about this wrong orders but still nothing is happening yet. What they impliying is that i have to take a taxi and incure extra cost just to take back this items, when I first place an order they didn't tell me about collecting the items the showroom, I am not happy about my order. Is not my fault that they delivered what i didnt order. Now i turn to loose interest on homechoice. I am not happy. My initial order was 2 one seater couch cover and 1 two seater cover, they delivered 2 two seater couch cover, then i notified them then the place another order for me which is order number ***4 for those 2 one seater cover but now its defferent design. How can i use defferent design of couch cover in my sitting room, its useless to have them. I just need about this store.
