useless personnel

I had a contract with Netstar for my cars that ended in 2021. I then called them to inform that i wont be renewing my contract. I then further send them email to Finance they requested my ID i did send them. to this day nothing is happening every month since Dec 2021 they wanted to debit my account. I wrote another email requesting them to stop nothing happened. to my surprise today I was called by lawyers telling me I owe Netstar money. What a hell is really going on here. Is Netsar personnel still working or their offices are closed. I have never seen such a useless tracking company in my life. they use tell me my is jammed whilst parked in the garage really. jerrrrr sies maaannn
