Appalling and frustrating service!!

It started in January when I received continual battery disconnect messages, eventually I realised that the battery disconnect messages resulted in me having to continuously jump start my car. In beginning of March 2025 I got hold of Netstar and reported the issue to be told that even though I had paid with my car purchase an upfront 3 years that I need to pay for the unit to be upgraded (they THINK this may be the problem) as it was out of it's 1 year warranty. I was also informed that I had a second unit in my car which may be causing the battery disconnect messages. The second unit was cancelled, however I still was receiving batter disconnects and having to jump start my car. I again contacted Netstar and left 3 messages over a space of 2 days for the team leader whom I had spoke to previously, to contact me. He never returned my calls. In the interim I had to get a towing company to jump start my vehicle 3x in one week, plus a kind gentleman at a shopping centre. I couldn't take it any more. I also had to pay for Battery Centre to charge my battery. On 27th March 2025 I cancelled the unit and requested that both units get removed. By the 2nd April I still had no contact from Netstar as to when they will be removing the units. I called in to be advised that someone would contact me that day to let me know when a technician would be coming out. On the 8th April after making 3 calls to Netstar totally 24 minutes, including a customer service technician putting the phone down on me, I received a call back to say the units would be removed on 10 April. Eventually that afternoon the units were removed. Now to get the my refund for a unit that I had only used for 20 out of the 36 months. On the 10th April I called into Netstar's finance department and was put through to the lady who had calculated my refund. Upon receiving the amount to be repaid I was not happy (don't take any add-on service through We Buy Cars they add-on a mark-up to the actual cost). She advised me that she would email me a breakdown of the refund and then give me a call back. Netstar has charged me an admin fee and a hardware fee (despite the taking the physical units) for the cancellation, none of which was discussed with me telephonically! To date I am still waiting for that return call! This now becomes my next fight. The saddest thing for me is that the majority of companies in South Africa with call centres provide NO customer service. People are employed and they look at it as just a job. They don't take the time to really assist the customer to find a solution for the client. Not at any stage in all my interactions with Netstar did someone take the time to discuss my options and how they as the service provider can solve my problem. Every company should take look at the customer service Dotsure provides. Their customer service is impeccable. They know how to retain a customer!!!
