Horrible Cancellation Process and Experience

On 1/10/2019 I was given a cancellation quote of R916 by a gentleman who never made a note on the system apparently and he said that I still have 3 days to accept the quote. After discussing the amount with my husband I phoned back to cancel the service with Netstar on the 4th of October 2019 and was then informed by a lady called Amanda that the cancellation is now more than R1000 because there is cancellation fees which wasn't discussed with myself in the first phone call, I asked her to go back to the recording and give me answers as to ehy the price increased so dramatically and I also requested confirmation that my previous insurance no longer had access to the tracking information as they are ********** in their business dealings and to date still haven't had any feedback from Amanda or Netstar for that matter. I phoned again today to cancel my Netstar contract and spoke to a gentleman called Goodwill and after holding on for more than 6 minutes to confirm with the retention department I received a quote of R979 and again I asked why to which he said that he is going to ask Amanda to listen to the recording to get answers for me and he will get back to me. Upon asking Goodwill when more or less I can expect a call from him he said that it will be before 1pm (at the time our phone call ended it was 12h30), I received a sms (not a phone call) at 12h49 stating that my enquiring ref no is CAS-***-S5Q2. I am fed up with Netstar's empty promises and bad service. Also do not even consider getting a unit from them because their service in that regard is just as terrible, we have a Ctrack unit installed in the same vehicle who's service and communication is excellent and were forced to take the Netstar unit by the insurer at the time and they do not even bother to contact you if they pick up that you battery is disconnected instead they send a sms which in a emergency is not going to work? I have also said on all 3 of these phone calls mentioned this issue with them and again nothing from Netstar's side not even a apology or a empty promise of further investigation
