Pathetic service

I purchased a Russel Hobbs microwave 21 Oct, delivery took forever even though I marked it for urgent, it was delivered 5 Nov. I called it on the 13th May as the microwave doesnt switch off so the plug had to be pulled of the wall, then the door refused to be opened as food was already in it. I then dropped it at clearwater hifi corp and was given a turnaround time of 5-10 days. Sabelo Mabaso that is the customer care agent clearly has no customer service skills to be appointed in such a position as I need to follow up with him......There is a problem with the microwave, therefore Customer service response was either, can I refund your money or can I replace the item. Not allow a client to go 3 weeks without a product.......I require an urgent solution as Im not prepared to wait another day.
