bad service and treatment

November 2019 i bought new car and request for the device to be change from my old car i then paid the admission fee and they told me that i ll be contacted for the installation of the device but that did not happened up until the country was close for covid and i then call them and ask what's going on since u promise me 14days to install the device and i was paying for something that i don't have so when i phone them none of them is willing to give me answers and it's my money you are debit every month without any problem and i never skip payment and in return i m being treated this was since my query was escalated on mid april 2019 still now i m waiting for their response
