TRACKER SALES REPRESENTATIVE MISLEAD ME

I recently purchased a new vehicle for my company, and removed and added a vehicle. When signing up, I asked the sales person what device we currently had, as I would like everything to be the same as my other vehicles. She the informed me to tick connect, as that is what my vehicles have.

To my suprise, we actually have the retrieve UNIT and not the connect. Now tracker wants to charge me R7000 cancellation fee for misinforming me about the unit i currently have. I have tried escalating this with tracker, only to be told that i ticked the connect on the form (I called them when filling this out as there are 14 different units to choose from). Then I requested them to please listen to the recording, but they never get back to me. I have also requested a manager I spoke to to also send me the recording so i can prove what was said, but also never happened.

I am not sure how i could escalate this matter further, as it feels like I was taken advantage of, and now I need to jump through hoops to rectify an issue, that was caused by the sales representative. The connect is also only R50 more per month, which is fine, but the connect unit sends me about 10 notifications a day, with tracker calling me at 4 o clock in the morning about nonsense. I DO NOT WANT TO BE CONTACTED EVERYDAY ABOUT MY DRIVER DRIVING IN SOWETO.
