Cartrack headache

I started using cartrack in October after buying my first car and I feel this is why this company thinks they can do as they please and get away with it.

They have few packages to choose from and I chose what suits me best, then last month one of their sales person called me and said he wants to explain how one of their extra serves works. Listen to the guy and the next thing I know the guy is reading me terms and conditions I thought maybe that part of their process. After ending the call I get an SMS saying there was an addition on my package which means an additional amount is added in my subscription, I called in to tell them That I do not need the service since same things they offer, it's what I'm already paying for in my insurence. And take note of the fact that when adding a service you still need to call them to activate the service on the app, now I'm told I need to pay for that service that I never agreed to and never activated. I went to my bank and reversed that amount they took without my consent but 2 weeks down the line they debit again meaning they can do as they want
