Very poor service I have been a customer since March 2018 they only provided me with a tracking report from 2023 March to 2024 August - currently no functioning tracking device in my car and they keep on demanding payment

Very poor service I have been a customer since March 2018 they only provided me with a tracking report from 2023 March to 2024 August - currently no functioning tracking device in my car and they keep on demanding payment . They do not respond to my questions and requests for repayments and are generally just defensive or rude /or transfer you to another consultant. I tried to escalate to ***rack .com or via the MIOSA. I am stressed , frustrated and helpless. Tebogo, Mpho, Kgothatso, Koketso, Obakeng , list is endless.
