Netstar not cancelling my subscription

Firstly thank you for the years of service to Netstar. It has been good before I start

Ive had Netstar for many years.

I sold my Haval in I think August 2022. I called Netstar to confirm my subscription with them has been cancelled and the gentleman confirmed that it is indeed cancelled. The October 18th I sold my Bakkie, which Ive had since 2017. There were issues with the Netstar phones at the time so I sent numerous emails with no reply.

I moved to Germany, so I cannot be reached on my SA phone anymore. After reversing the debit order, cause I sent numerous emails asking them to cancel the subscription they call my dad. I sent through all the emails i sent to this point to my dad and then someone from Netstar contacted me saying I owe R1500 odd via email. I told them that this info is false as I sent numerous mails to cancel my Ford, and the Haval has been cancelled.

After 2 emails back and forth, this person stopped contacting me completely. Few days later I receive another invoice, again Netstar invoicing me for both vehicles.

Few days later I get a mail from debt collectors saying I owe R2100 odd for both vehicles.

I have sent a mail every single time I received something, just with no reply

PLEASE CANCEL MY SUBSCRIPTION. I DONT OWN ANY VEHICLES IN SA ANYMORE.

Thank you guys

The number is for my dad as I dont have an SA number anymore
