Damaged Goods and No response

I ordered a Two-tiered Dish Rack from Magic In The Box on the 19th of March via Groupon. I received my goods only on the 6th of May after numerous times following up. That delivery was extremely delayed in addition to being told it the colour I ordered was no longer available. I received the goods that were in really shabby condition and I complained immediately on the 7th of May after I had received the item and included photographs of the scratches that were on the item. I was promised by the Returns department on the same day, the 7th of May to have the item collected asap. The item is still with me- not collected, I was never contacted ever again by Magic In The Box. On the 13th of May I emailed again complaining that after being promised the item would be picked up, it had not. I indicated in my email that I'm no longer interested in an exchange and that I just wanted a full refund because clearly their service is pathetic and they don't care about their customers. I maintain, I want nothing to do with Magic In The Box ever again I want my money back! THIS KIND OF SERVICE IS APPALLING and no one should have to put up with this. Magic In The Box must get their act together!
