Charged for removal of tracking device by Netstar Booysens that was never removed .

I was charged for removing a tracker device by a Netstar fitment centre in Booysens, Johannesburg in 2020 but was de*****ed by paying for the removal of tracking device but no removal was actually done. I only found this out when I installed a new tracking device from Cartrack in my car recently. I contacted Netstar customer service department not once but twice, outlining the situation and requesting immediate response. Regrettably, I had not received any response from Netstar regarding this matter despite the seriousness of the issue, until I threatened to go onto social media. Thereafter I was told I needed to provide proof that a payment was made. Who keeps payment details when you getting rid of a contract and also would I try and ***** a measly couple hundred rand from them?? I advise all Netstar clients to be aware of ************ fitment centres that rip people off for a service that is never executed.
