Very Angry client

In my entire life, I have never seen such bad service from my insurer. They are a nightmare. After my windscreen was cracked it was replaced by their service provider, My Glass from Pretoria, I started experiencing water leaks in the vehicle. The service provider was contacted and came back ,however they did not sort out the issue and instead I experienced more problems. An assessor was appointed by Miway and completed a full report , arranged with My Glass to come back again , this time it was worse the just poured water on the windscreen and said they don't know where the problem is however they will also send a report. On the 4th of February 2022 it was raining and the leak was worse, I took pictures and videos sent to Miway and no one responded to my complain. I have been calling the insurer for the past nine days and got promised that a manager would contact, to date I am still waiting . I have contacted them at least every second day and all they say is that they will call me back. . I cannot drive the vehicle when it rains because the water simply runs down from the roof pillars. The carpet is is getting damaged and the car is smelly due to the water. I have begged them for more than 2 months to assist me and to date they simply ignore my please...mind you at the end of the month they debit my account. They do not care about their clients and they are full of empty promises. At the same I'm receiving calls from their sales department offering life cover....the nerve! Very angry client!!!
