Keep on HARRASING ME. SUPER BAD SERVICE DONT USE MATRIX

I requested in January that my Tracking device and contract be cancelled. On the 16th of January 2023, I Received an email stating to cancel the contract I needed to pay R302.00 The amount of R302.00 was paid on the 1st February 2023. After months of harassing me telling me I still owe them my monthly subscription they eventually realized I cancelled the Contract BUT is still owe them R107. they are continuously Harassing me stating I owe them money and they are going to hand me over if I don't Pay that R107 before the close of Business today. Well I should have listened to everyone who told me NOT to use Matrix Tracking for my Car
