Netstar Shocking service

I called the Netstar call centre more than 6 times during 12-16th October 2020. I confirmed with the call centre that my vehicles was sold and as the existing unit was out of warranty the unit could not be transferred therefore that contract will be cancelled. I only managed to confirm the new installation on 19th October 2020. The unit was installed and active. The next month debit order I have been doubled debited for both vehicles. I sent an e mail on the 24th november 2020 to query this no response. I call the call centre and i have been transferred to several departments with no help. My query has not been resolved and escalated again and Sifiso that was transferring me cut the call. Your team is really dissapointing and your customers service is zero. I even had a call today to confirm if i still need an installation.
