Non existent service

I claimed from King Price for a shattered windscreen and I was informed they use 24 Fix for all glass repairs. I got a call from them on the Friday (17/04) and I asked the lady to arrange it for the Monday in JHB as I work there, a technician would have phoned me to set up an appointment. On Tuesday 21 April I phoned 24 Fix to ask what is happening and was informed by Shannon that he will check and phone me back. Which never happened, I phoned again on 22/04 when I was told there was no stock, and ordering takes one work day. I involved King Price at this stage again to assist. They then made an appointment for Saturday 25/04 to fix my windscreen, only to be informed on Saturday that they did not get stock and it will be done 28 April at 11:30, irrespective of how many times I have to change plans. On 28 April at 11:45 I phoned 24Fix to enquire where the repair person is only to be informed that he did not get the stock and will not be coming. Not once has 24 Fix stuck to a date or informed me of progress or lack thereof. I do however get reminder to pay my excess in every communication with them, but about client service they do not care....
