Mix Telematics non exitent service

I have been a customer of Mix Telematics since 2000 and of late their service has really degenerated, it is actually non existent!! On 7 September I received an e-mail stating that my account cancellation has been processed. However, I never asked for the cancellation and no one contacted me!! I phoned and spoke to Bradley on the 9th of September and he assured me that it was an internal error and that all has been reinstated. However, to my shock, horror and surprise I activated the Geolock on 5 October, thinking that all is working and well. On 6 October (today) i realised that I never deactivated the Gelock and that no one phoned me. This means that, God forbid, if my car was ****** the insurance would not have paid out due to the tracking device not working!!!! No one ever reactivated the account BUT they keep invoicing and receiving money. ****** ridiculous service!!!!. I phoned this morning (06/10 - 10:49) speaking to Caroline and explained the whole situation and asked for a full explanation of the situation. At 11:38 I received a call regarding the Geolock alarm that should've been yesterday! As yet I have not received any mail explaining what happened or an apology!!! This is extremely bad service and I hope the insurance companies take note of this and stop forcing people to put tracking devices in their cars as it is of no use!!!!!
