[URL Removed] delivery company doesn't deliver

I ordered and paid for a Canon printer online on 28th January 2015. Delivery was shown to be on the 11th of February 2015. Despite this long delivery time, it suited me as I was taking a 10 day trip to Cape Town and would be back home on the 10th February to take receipt. When I was home, no delivery happened. I tried contacting [URL Removed] and the delivery company by email and phone. After two days of no response, I thought I had no other option but to cancel the order. On Friday 13th February, I received a phone call from a lady at [URL Removed] After explaining the situation, I requested either the printer or my refund, quickly. She explained that it would take 5 working days to process. When I complained, she said she would have to escalate the problem. I said that would be fine. The next I heard was when a different courier company arrived at my home on 17th February to \collect the parcel that was being returned". My account on the [URL Removed] website is still not showing my credit"
