Bad quality product and the worst service

I placed an order of a double bed through Mr Price Home online shop on 5 Aug 2015 and received a damaged item on 13 Aug 2015. I phoned the call centre the following day to request for exchange and been told the item was out of stock, they have to place an order from their supplier and it will take about two weeks. I told them I have no problem as long as the damaged item will be replaced. A few hours later they sent an email told me they are not getting new stock anymore, however they can offer me the queen size but I have to pay the price difference. Two days later (Sunday, 16 Aug) I saw the double bed is available online again, I placed another order immediately with pay in store option to avoid the payment so they can replace the damaged bed with the new one. Sent them an email on Monday to ask for exchange again and I have been told there is still no stock. I gave them the new order number I placed on Sunday and they said they will check it again and get back to me. There is no more feedback from Mr Price Home since then. This is the worst service I have ever had in this country. I am disgusted with the service provided and will not spend a cent at Mr Price in the future.
