Disgusting service

I bought and paid for a Samsung microwave on Thursday the 25th November at the Strubens Valley store. Due to the strike and not having a forklift driver to reach the product on the shelf I was told to collect the unit the following day which was Friday. Upon arrival we were told "sorry the units are now sold out but we will refund your money". On the Monday I went to see Devon the appliances manager and he said I was to give him until Wednesday, the 1st December to sort it out. It is now Thursday the 2nd of November and still niks! Nada! Not even a phone call. I have tried telephoning their listed number but guess what! Just voice messages! Disgusting service! They take your money but don't stick to their promises.
