Netstar Customer Service

I requested the installation for two vehicles on 25 May 2021. No appointment was made for installation after one week. My insurance company offered to help and I gave the reference numbers received from Netstar. The installation was eventually done on 7 June 2021. I sold one vehicle at the end of June and cancelled the one contract online. Nothing happened and I still paid the monthly payments. Yes, I am very much aware of the T & C; especially the cancellation terms. I went to the Rustenburg office when another debit went through on 1 August 2021. The staff was very helpful and I managed to get the contact cancelled. I want to get back online (Customer Zone) to "view and update subscriber and account details". What a challenge. Reset the password and the given password does not work. I can not see any support details. customerportal.netstar.co.za tells me the username exists already but then I can not log in. I was with Tracker before and I am counting the days until this Netstar contract expires so I can move on.
