Discovery Insure pathetic service

We have been a client of Discovery insure since around September 2019. My wife's car forms part of this insurance and used the window mount tracking unit to track her driving etc to get bac as per advertising. In the last couple of months., the unit would not work properly. We enquired thru our broker, and was told that the problem lies with the Huawei P30 phone my wife is using. How is that even possible. She had the phonesince June 2019, and it worked well at start. When did they realise it doesnt work with Huawei. When are they going to tell customers. They are *****ing from us by not disclosing, or contacting us. My broker have requested that Technical contact me to discuss. Nothing I find this appauling and seek advise on the way forward.
