Cartrack Robbing its clients.

On the 28th of July I sent an email to car track to downgrade my package to the original R99 plan that I had initially purchased, due to Covid-19 I explained that I am not financially able to pay the package that I REQUESTED TO ADD THE EXTRAS, I was sent an email by Thapelo Tshilwa telling me that to downgrade I would need to pay a once-off R350 "downgrade fee" in order for the technician to come and swap the tracker units, I asked why swap pay a downgrade fee for the units to be swapped if when I upgraded no one came to install and "upgraded tracking device" it is the same unit I got with the R99 package I recieved no further response, I am not happy with tracker that during these dire times when we are facing manhy challenges finance being a major one due to job cuts and so forth that car track is trying to milk their clients, I mean when they upgraded the R99 tracking device package then why didnt they come and install a new one for the upgraded plan?
