Horrible service, Empty promises

I am very disappointed with the service I received from cartrack, I sold my car and informed them Thursday the 16th to come de-install the device and fit it to my new car. They sent me a scheduled time for the same day but they never went there to remove the device let alone to inform me what happened. Everyday I've been calling them and I will get "we are sorry mam we are assigning a technician to attend to your query" till today almost a week now the device that I am paying for it's still on the car that doesn't belong to me and my car doesn't have a device. I've been using cartrack from 2020 and I have never missed any payments but the service I received recently is sickening and I doubt I will renew my contract when it ends after this treatment. And the sad thing is that when comes debit order date you guys will debit for the installation that didn't happen. And I've been telling them that the car is under offer to purchase with the dealership and should someone buy it with the device you guys will charge me again as if it's my fault now that you didn't go to the dealership to remove the device.

I don't wish this horrible service even to my worse enemy😡😡
