Bad Customer Service

My sad story I have been with Iwyze for four years now my other disappointment this year is having being forced to fit an after market windscreen(which is a safety part on my car)on top of that my car take a windscreen with sensors to make it even worse my claim was registered 13August the supplier told me my Original glass with sensors is being ordered as it authorized by Iwyze and I have been the one making follow up,being passed from one consultant to another because of the query I made of why am being told now things have changed I have to put after market windscreen parts,when initially it had been approved for my original windscreen .....1.I got bad customer service both from Iwyze and the supplier send from pillar to post...2.now they want to make me put a an after market windscreen(windscreen which forms part of a safety part of my car)when I pay fully without fail now my safety has to be put at risk with after market windscreen part whiles I pay insurance fully....3. Am owning a 2013 car which has lost value and as a loyal customer I haven’t gotten a offer to reduce the R1504.85 that am currently paying........4. I had an accident 2018 September and the second party was at fault am yet to be compensated for the excess fee of R3950 till today wasn’t not compensated,am at the edge of cancelling this insurance because of constant bad service when I have to claim when I fully pay without fail what happened to treating loyal customers with respect and good service.....regarding my windscreen am being passed from pillar to post and why do we insure with Iwyze when we get such bad service.
