EXTREMELY POOR CUSTOMER CARE NETSTAR

I sold my vehicle in October 2022, called Netstar in November 2022 and asked that they cancel the tracker agreement. I follow up with an email. They asked that I pay a certain amount which I did. March 2023 they are still calling from the finance department and stating that I am overdue in my monthly payment. Extremely poor communication between departments and poor service delivery as well.
