Extremely Poooooor Service Rendered

I have never received such a poor service from a tracker company like Beamie. The customer care was quick to cll me when I was signing up for their devices. I sold my car in July 2022 and I have been sending email to the customer care to deactivate my Beamie on the car. everything I sent an email I receive a reference number after that nothing happen. I even tried their whatsapp platform and I have receive the reference again and I will get a call from their agent in 24 hours. I have 10 references nothing happen. I have tried to call the customer care it just ring then it discount even if you can call for ****** car. Every month you receive an invoice for service that it is never been rendered. I just regret the day I signed up for the service. Now I am stuck with their stupid contract term.
