Cartrack useless services

I decided to fit a cartrack tracking unit into my car at the begining of 2020 ,all was well until 2021 when i bought another car and wanted to transfer my tracking unit as i was selling my old car ,cartrack agent told me that i need to pay them R870.00 to have my tracking unit de-installed and re-installed on the new car ,i asked them if i can pay when the transfer on the unit is done but the agent told me that i need to pay for this upfront before and transfer of the tracking unit can be done ,i then proceeded and pay them ,it took them 3 months to de-install and re-install the tracking unit onto my new car ,everytime i phoned the call centre they had no answers for me and all they could say is sorry they tried multiple time to put through to the branch manager of the pinetown branch which was not possible cause the call would always get cut off ,in the time they took to complete this request i had already sold my old car and the car was no longer in my possession but with the new owner ,i was soo ****ed off with how pethatic the level of service i received from cartrack ,i sent numerous emails to Kavitha Lalla from CEO escalation and she emailed me basically asking me to give them one more chnace to rectify they inadequate service ,i gave them that chance but didnt receive any gratitude ,later in december 2021 i lost my job and had to sell my car so i wanted to cancel the cartrack tracking unit service ,they said i would have to pay them R2442.00 for the remainder of the contract which i was not impressed by cause the installation was free but now i have to pay for the cancellation ,i had explain to the agent i am not working at the moment and when i start working again and get money i would pay them the cancellation fee ,they continued to debit my account for the amount of R218.00 ,they agent later called me and informed me that i have to pay the balance of R1556.00 which i explained to the agent and agreed to pay half the amount in the first month and the other half when i get the money ,the agent agreeded with that ,the next month a agent from cartrack called to say that i must pay the full amount of R1556.00 and that they are gonna put my account on the credit bureau to be blacklisted and that i would have to pay an added amount of R1800.00 to remove my name of the blacklisting department ,i explained my previous conversation with the previous agent but yet again all the call centre agent could say was they were sorry and i was fuming would have inadequate the level of service was ,i proceeded to pay them the balance of R1566.08 and even sent them the proof of payment this was in july 2022 , now i see on tuesday 22nd of november 2022 i received a sms saying that cartrack has blacklisted me due to continuous none payment,4 months later this message has come to me which i think is a big **** ,even if did owe them that why did they take 4 months to notify of this so they waited for interrst to build on this amount so they can exploit me for more money ,i think this whole thing is horse **** ,they didnt take into consideration that they failed to uphold they service when i paid to have my tracking unit transfered ,these guys are making empty promises to they clients ,i didnt see any reason to blacklist me as i paid the amount i owed them in july ,very disappointed with cartrack who talks a big game but cant stand by they words ,i will have to share my experience with others on social media just as awareness to other who are using they services .
