Poor service from DQ side

I included vitality drive on my discovery car insurance and the DQ is absolute nonsense and i reported mine was recording the points, instead of being assisted i was sent left right and center none of them was able to assist. I am taking that b@#%%^& sensor off my windscreen and i want the money that i have paid back cos i have been failed from day1 with this DQ and even after talking to the phone so many times i am still not satisfied
