Discovery Insure reward trickery…

I constantly wonder whether the hoops I am made to are worth being with Discovery at all. For nearly two months I have tried to communicate issues with my Drive sensor on my vehicle resulting in drive points and rewards not being assigned. Now due to work commitments I cannot get the vehicle to a Tyger Wheel and Tyre to replace the sensor as they have finally asked to do as the vehicle is stationery and I am working long hours for two weeks now yet they cannot deliver the sensor or award the points as a ‘sensor needs to be fitted’ which I already have but which is apparently faulty as they have taken their own sweet time to figure out. I am constantly being tested by Discovery and all their services and it’s getting tiresome.
