Useless Netstar

Wish I could score lower than 1 star.... We were insured with Dotsure where Netstar is included in your premium (makes sense now why a useless insurance company would use a useless tracking service). While we were insured with them, both my husband and I traded in our cars. Both times an amount was deducted off my account to pay for the new tracking unit in the new vehicle. December we moved to a different insurance company, but stayed with Netstar as they would charge us an amount for contract breach.... December, January and February the correct amount was deducted from my account. All of a sudden they deducted R580. For two vehicles! When I phoned, they said it was for the 1 car that we did not own anymore (and haven't for 2 years). It was a mistake and the excess amount wil be put in my "Netstar account" for the next month. That was on 22 March. Since then I have been trying to get the old vehicles off the app and the new ones put on. On 20 April another R300 was deducted. Where was the excess amount owed to me? Phone on 21 April to be told their system is down, but she takes my details and tells me they will phone me back. I'm still waiting. Phone again on 24 April, to be told the 1st consultant gave me the incorrect info and this amount was a penalty for one of the cars we don't own anymore. That's when I lost it! All of a sudden her story changes and she says it was a mistake and she will have the money paid back to me within 7 working days. Today is day 7. Phone again because still no money. Firstly he says the money takes 7 to 14 days to reflect (different story from the previous consultant). So I ask if he can check my account to make sure it was done. Don't know why, but he takes my number and says he will phone me back. Still waiting. How is it possible for a company as big as Netstar, that used to be the leading car tracking service, is now such a useless company. No service, no call backs, different consultants each with their own story, about 20 different reference numbers (none of them meaning anything). I still don't have my money. Netstar *****s you money. And I know I wil get the generic "One of our consultants will phone you" reply on this, but I'll wait until the end of time for that phone call as I am still waiting for the previous 2.
