TELEMATICS - Worst ever SERVICE, VERY FRUSTRATING

Matrix is the worst ever on service, I have been trying to cancel since dec with no progress................1-i don't have the vehicle anymore, 2-discovered that i was now debited for 2 devices which i never consented to and still no explanation /clarification no consultations were done or any product info from them as a supplier to a client. Since dec 2022, till now June 2023 already, am still having to call and told the same story, no progress. MATRIX SERVICE very frustrating, on top of that they keep taking my money with no remorse. I cannot count how many calls I have made to them but still no progress. All they tell you is as long the account is active, we will continue debiting you. No customer service support at all, no remorse, no genuine service from this company, Ignored emails, calls, unresolved cases, most frustrating , if u don't call them , you won't get any resolution to your cases and when you call them , again you will lose airtime cause they are going to transfer you to a dept where no one answers and your call is going to be cut again, so you will call them 3-4 times to actually speak to someone.AM VERY DISAPPOINTED WITH THIS COMPANY.
