Mr Price Home is Pathetic

I recently purchased 3 x sleeper couches. At the checkout it only allowed me to make the purchase of 2 X Teal colour and I had to choose another colour to make up for the third couch. So I chose the natural. Today I checked the Mr Price home website and I found that they now have more Teal couches available. I called the customer care to request a swop for the Natural colour to the Teal colour but the rude and arrogant agent insisted she could not assist me. I questioned as to why seeing that my order has not been dispatched as yet. Instead she insisted that she would cancel the order and refund me. My request was absolutely simple, just to have the natural couch swoped for the Teal couch as that was my initial choice but they didn't of stock for 3 couches. Then she says that if I wanted another Teal couch I should place another order and incur an additional delivery charge. This kind of service is absolutely outrageous, especially if my order is still at the warehouse. I will not be supporting Mr Price Home ever again with such terrible customer service.
