Poor Service from We Buy Cars Midstream

We Buy Cars Midstream and their compulsory insurer, Innovation Group, both refused to take responsibility for a missing navigation disc (SD Card) which was only discovered when trying to use the navigation system after taking delivery of the vehicle. My advice to future customers of We Buy Cars is to make absolutely sure of everything in the car (including navigation discs) before you take delivery because their aftersales support is non-existing. That leaves you as consumer totally on your own.
