Bad Service and they lie to you

I ordered the Alva 9kg Gas heater yesterday. Before I placed the order I phoned to make sure you had stock, I was told there is stock. I immediately placed the order. Half an hour later ur site still had stock. An hour later I phoned wanting to collect from CPT warehouse to be told there is no stock. I had to keep phoning ur call centre as Nicole just stopped phoning back. Then the supervisor Sarah never called back and I had to constantly keep phoning. She cant do anything about my heater, even though I ordered when there was stock - I was basically told \tough - you have to wait 10 days". The manager"
