Netstar Go (Billing after cancelations?)

I requested cancelation of my netstar tracking products after I sold my car. They cancelled the tracker but there was still a amount for Netstar Go going off. Netstar told me they cant cancel it I have to request cancelation from Netstar Go?

Then the rabbit hole started:: I cancelled my Netstar Go product in May 2023 and was informed there was a 30-day notice period via email. Despite fulfilling these terms, they continued to bill me R65 per month long after the notice period ended. Repeated attempts to resolve the issue or obtain a refund were met with either no response or vague promises that never materialized. It’s incredibly frustrating to see ongoing charges for a service I clearly cancelled months ago. This experience has been unprofessional and disappointing, and I would strongly urge others to consider alternative providers to avoid the same hassle.
