No delivery, Management unable to resolve my query

I purchased a gas stove on Friday 6th Feb'15, as well as paying for delivery. Sat 7th I got a sms & a call from them inquirying the area i stay in. They confirmed they had a delivery in Newlands, then deliver my stove then to Alberton. I waited till 6:30pm but to no avail. <br> <br> I called the store on Sunday morning and spoke to Barbara who said she would call me back. But she didn't, I had to call again and spoke to Cynthia. Barbara then only called me back telling me she couldn't get hold of the courier named Isaac. I then spoke to a Manager, Milton. Had to convey my query again but he wasn't helpfull then handed me off to Barbara again who said she'll call me back.<br> I called AGAIN!!! Spoke to another manager named Clive who said he'll call me back. He did call back saying the courier was in Benoni and that they said they couldn't get hold of me. Also that it would take 4 hours before they could find a car. Long story short....No delivery was made this weekend. I was even asked to fetch the stove, i have a sight disability and they knew this when i paid for the purchase & delivery.
