Worst service ever

I have been contacting Nestar since last year regarding a unit that I had with them and been asking that they cancel the contract howeii have been taken from pillar to post being told it's the insurance company that should cancel it and when I spoke with Dotsure they told me it's cancelled and I can arrange for the removal of the unit which I have been calling naster and they could not assist and told me I will get a call back .no one from their customer service department called me. From October last year . They don't even know their own pricing in terms of the unit removal, one tells me this amount the next person says another amount, insurance also says a different amount but because I need this unit removed I told them I will pay as long as the unit is out of that car as the Battery is being drained. Last person I spoke to was Thabo in customer service who promised that they will call me to schedule an appointment but even today nothing. I specified that I'm available at 12:00 or after 18:00 as I'm not able to take calls at times . I have been waiting and now I had to buy a second battery In a space of 8 months.
