Whirlpool disgusting customer service

I have had to sit for almost two months without a working microwave bought from Dions Wired (The grove). This was a whirlpool product. According to their rules I booked the unit in for repairs. Technicians came to assess the problem. After arriving up to two hours late the two individuals informed me that we would have to wait up to 15 working days for the repair to be made. This happened on the 30 November and I was still waiting for a response from whirlpool on the 23rd of December. It took me (the client) calling whirlpool in order for me to hear anything from this ill run company. To which their manager (Melissa) told me that the repair of my machine would not be taking place after all. I was shocked. Melisa also then told me that I would have to return to Dions to get another machine. I think whirlpool can do more.. I asked them to have the machine delivered to me to which Melisa said she would contact her manager and get back to me. She has yet to do that. I have left 4 messages with the call center for her to contact me but she has shown that she is avoiding my calls all together. This has shocked me greatly and I think that whirlpool needs to do something about this.
