pathetic service

DISGUSTING SERVICE On 1 June 2021 I notify the cartrack that I sold my car and they need to uninstall the device and the panic button and my account is debit with R870 although the job was not done at all what........., I contacted the callcentre numerous time still no luck . Today is the 06 October 2021 and nothing has happen. I tried everything but cartrack wants money producing poor & false service its totally unacceptable.
