Bad service

I bought a 3 piece defy stove on the 3rd of August and i was told the stove is not available they will contact me as soon as the stove is available. Around October they called me to come fetch it when i got there they told me they gave the stove to someone else they'll contact me again when it's available. Now 2nd December I go to the store at waterfall mall to ask what exactly is the delay the manager tells me he'll personally call the warehouse and ask them when will they deliver and then call me back the next day. On the 3rd December no call from the store whatsoever, then I call and the manager tells me he's busy checking for me on the computer he'll call me back. No call I call again request to speak to the sales person who sold me the stove they tell me he's on lunch he'll call me back when he comes back. No call. I call the manager again, his line I'm told is busy. Really bad service from and store manager and the sales person and I just want my stove.
