I have a black box fitted in my car. On 3 occasions the driver was speeding, I was able to prove this as I have an app that tells me the time, location and speed they were doing. The response I got was "They have to speed to check the brakes!" They said I needed new rear brakes but I had them fitted new 3 weeks prior to this! They said my engine tray was cracked and needed replacing, on return of my car had a mechanic look and there was no engine tray there! said my drive belt was cracked and needed replacing and wanted to charge me an astronomical amount I said no I would go elsewhere, again another mechanic checked it and no crack seen! tried charging me £35 for specialist oil! They have offered me £10 as a good will gesture the next time I use them, I have politely told them to put that £10 where the sun doesn't shine. NEVER again will I use this awful company!
