telematics never works and rewards payout claim is just to make us pay for terrible customer service

2months of calling and sending emails via app and no one has ever returned to respond, My app has not been working for 2months now and this app has not recorded most of the trips that I have personally even sent as proof from the car tracker records. Then as this is not done I have not been paid out my rewards since October nor is anything recorded on the app. I have deleted and installed it 3 times if not more. Mind you have double debited my account because for some reason the system didn't do change of bank details! then I get an email that my policy has been cancelled???????? you call and hold on for literally over an hour with no one answering the phone at that call centre! like its so tiring to deal with this yet all I want is good service. can someone get to the bottom of this nonsense and get this app working properly and then pay out the outstanding rewards than just always taking my money!
