******** contract dispute

I made an enquiry a few months ago regarding cancellation and they told me I can only cancel after 24months, a few months later I asked again and they confirmed that I'm reaching my 3year time period so I requested immediate cancellation and had to send an email at least every 3rd day with no reply. I stopped my debit order, they just reactivated it and deducted money.....last week I wanted to use the app for the first time since I became a customer and found i forgot the password. they give one the option to ask for the password via a WhatsApp procedure which I followed......my car was MIA and I really needed to get into the app....I tried to get my password several times and each time they rep**** they will not validate my request because I do not exist on their system.....but they have been deducting money from my account for almost 3 years.... luckily I have a friend that works for a security company that traced my car via their contacts and I'm not even a customer of that company......how is any of this fair or legal, I want the device deactivated and the contract cancelled without extra fees. thank you

I am now really speechless.....even after Matrix failed to grant my request to cancel the contract which is approximately 6months over the 24months required, and failed to deliver the service they are suppose to give nor where able to assist me in locating my car, they still insist on a R519 cancellation fee......I really think this is outrageous and Hellopeter should take this matter further.....I am not paying them anything to cancel there non-existent service because my contract by law was already expired
