Dissapointed

After having cover with dotsure for the past year i also received a tracking device from altech netstar included in my premium, my vehicle was recently sold and i paid for both de-installation and re-installation for the tracking device, however i feel that i should not have to pay re-installation as i am again a dotsure client with the new vehicle. On 22 March the tracking unit was installed in the new vehicle, however after phoning twice the tracking telematics was not showing and it states the device is not linked. An appointment was made, however the technician pitched a day early, i then again spoke to their office and the technician was supposed to come the next day, however almost 2 hours later than the scheduled appointment i received a call that the technician was late, i had a meeting moved to later that day due to this appointment that was not upheld and unable to then allow the technician to come later. I was told that i will be contacted for another appointment and now 2 weeks later i still have not been contacted. I want to cancel this policy as i paid and are paying for a service i am not receiving. Utterly disappointing!!!
