Inconsistency in tracking of vehicle

Received bad service with cartrack, one of their control room operator claimed that I was called after they received a notification that my battery is being tempered with. I requested for the record of the actual call nothing was provided instead I was offered 1 month free which I refused and requested that an investigation should be conducted internally while my account is held on hold pending outcome with a full report as to why was I not contacted, who verified my safety but they constantly harrased me with an overdue where I insisted on getting a full report of what happened on the day that they couldn't track my car I eventually told them to cancel my account as I was not getting joy with regards to my query being sorted. subsequently they handed my account to lawyers even after I told them that I want to cancel. My life and safety is worth more that what cartrack is promising consumers.
