Vitality GOOD or BAD?

I'm on Vitality Drive for nearly 2 years and for the last year and a half, I've been maintaining Diamond Status. Last week Thursday and Friday and this Week Thursday and Friday, I suddenly noticed that Vitality drive has been deducting between 40 and 50 points from me daily, with the message UNCOVERED TRIP. I called them to ask what is happening with that. Their answer is that there must be a problem with my phone and I need to put the phone on Air plain mode and take it off again and that will solve the problem and that they can not give me back my points, which means I will probably not make Diamond status this month. I have made peace with points being deducted for braking (Just normal braking), but this is now BS. It feels that they want to reward you for good driving, but when you do drive good, they want to find things to nail you. Discovery is already very expensive. I received a quote the other day from Sanlam on the same policy for nearly have the amount. Is it then really worth while staying with Discover?
