Complaint

I bought my car in 2021 apparently the dealership paid for my tracker I got debited twice and the debit order stopped ,I would test the device to see if I will get a call from time to time and nobody would attend to me. I then took a tracking device with another company that I have been paying then out of the blue I see netstar going into my account to debit a service I didn't know existed I requested cancellation and was told it's done only to be sent a cancellation letter that has another clients details. Please stop harassing me I don't need your horrible service and cancel that account I have a tracking device.
