GROSS SERVICE, MISLEADING THE PUBLIC THROUGH FAULTY DEVICES AND CALL CENTRE STAFF

The call centre called on a friend of mines phone offering her a device she passed the phone to me as i recently bought a vehicle. i signed up and on the 12th of april they came to install at my workplace I was informed i need to call to get the vehicle positioned and on Saturday I did that only to be told the device is faulty and a technician needs to come through which they did on the 13th april @ 3pm on monday the 15th i called again to get the vehicle positioned and again i was told the device is not picking up my location the app and their system says no GPS. i requested to cancel as i am within my cooling off period the gentlemen informed me to read my terms and conditions as cancelation needs to be in writing. i sent an email on the 16th of april 2019 @12:59 pm and i have not received a response from cartrack nor a courtesy call or an automated response for acknowledgement. i refuse to be financially liable for this device due to false marketing by cartrack, poor customer service and after service from them. i need an urgent response. i also inquired of when the debit will go off and i was told the 25th however R125 pro-rata taken from my empty account. you are supposed to provide a trustworthy service and transparent however you are worse than the people that ***** our vehicles. i need urgent answers and assistance oh another thing my carpet was not put back properly by the 2nd technician i can actually see where he worked.
