Terrible service / Only issues with Discovery and no solutions

My vitality drive sensor has not been working for the last few months, I have tried to phone, sent messages and put in a formal complaint regarding the issue. I only took the policy for the cash back system and yet I still have not been assist. I was told that the sensor unlinked itself and I must drive at least 15 min for it to work again - which I did and still nothing, then told my phone must have done an update and now that I must go back to tygerwheel for them to replace the broken item. I have had to phone in every time even after putting in a formal complaint. I have asked for at least a reimbur*****t for driving less than 200km but nothing. I was again transferred to the department and was on hold until the phone just cut out again.

I have cancelled my contents insurance as well with you as I was informed that all my electronics would be covered, even portable ones and when submitting the claim, I was told that it was incorrect information. I was then promised calls from a consultant to explain the cover to get full cover but still nothing months later. Terrible service
