Netstar money making scheme

I have been client of Netstar for a while with the tracking device for my car. Nov 2024 they approached me and advised that my tracker needed too be upgraded. Asked will this change the cost and was told nope. Agreed and the Tracker employee came and put in the upgrade tracker. December came I was charged twice, at first even though I was not advised this would be a fee for installing. Came Jan I was debited twice. Jan 27 2025 on a Monday took time to report this. I was told that the Netstar employee has created a new account instead of an upgrade. The lady apologised and advised that the funds will be reversed back that Friday into my account. Sounded like a straight forward process. No funds reversed, no follow up call from Netstar. Clearly they are making more money and have enough customers at this stage. Since I am just a number. Again now in Feb I called and explained the same story. This time the Netstar was defensive. Telling me I have two devices. Haibo I have one car that needs a tracker. Again promises promises, just empty words. Reversed 1 debit order Lo and behold I was double debited for the debit order I reversed and again charged twice. Is there anyone that is able to assist and fix the wrong by Netstar. Sad part I got another testimony about Netstar double debiting incorrectly. Pls find another way of making money. Soon I will go to Midrand to get my money.
