Netstar Vehicle Tracking Blames Vodacom for their Tracking devices Failing

I had installed a Netstar Vehicle Tracking system on the 8th of Febuary 2022. The system never worked from Day 1 and is still not working. I contacted Netstar on Numerous occasions to have the matter resolved. Finally after 2 weeks they came out and replaced the faulty unit. The same day the new unit stopped working !!! I have been contacting netstar now for the past 2 weeks asking them to change the unit. They have been making bookings with me and not showing up. They even stopped returning my calls. I last spoke to Nandi the supervisor there in customer services who promised to have the unit changed, this was over a week ago and to date nothing has happened. I called again yesterday I spoke to kagiso and requested Varthi who is Nandi manager to assist and again. Netstar is failing to replace this faulty unit. This is pathetic service from Netstar and their whole team. They have no reasons as to why their tracking devices don't work. Nandi went to the point of telling me that there is a problem with Vodacom and it could be Vodacoms fault as to why Netstars vehicle tracking units are failing. This matter is going on from the 8th of Febuary to date. Netstar has failed me as a client. Yet they continue to debit me for a service they cannot provide. I have fitted 2 tracking devices on my vehicle with Netstar as well as a panic button BUT NOTHING works. NETSTAR - What happens in the event of My vehicle getting ****** or hijacked ??? This is going on for 2 months now. Nandi and Varthi, NETSTAR should really reconsider your positions in CUSTOMER SERVICE. THIS IS UNEXCEPTABLE!!!!
