Poor customer care from discovery insure

I added a vehicle to my policy while removing another vehicle. Discovery charged me a pro rata amount which I have been querying an explanation for the more than 2 weeks with no explanation of how the amount was calculated. Every time I call I am advised that the issue has been escalated and there is no resolution .

In addition, Discovery increased my building premium during the process without prior notification. I also queried this and was to its a system error. I have asked for this to be corrected and reversed and to date still not corrected.

The call center team keep promising to get back to me with feedback but they don't bother following up. The service is poor. Considering changing the service provider.
