Bad service

I bought 3 blankets valued at R1800, I returned 1 that was faulty, in AUGUST 2015. Homechoice has not replaced it, they say its out of stock. They want to give me a discount of R200 for a blanket that worth way more than that whey they are selling it, I was called by Portia only once! its now 3 months with no response, im the one who is always calling them. Even the consultant are not helpful, or maybe they are only hired to take orders only, and today I spoke to the supervisor called Bulelwa, Damn she was so rude, that I had to hang up. I don't want their discount, I want to return the remaining blankets and all of my money including the one for postage that they promised to pay back, but they have not paid it even today, ****ED FOR DAYS!!!!!!
