Disappointing service

I received a letter yesterday informing me that my policy has been transferred from Regent to Hollard. My problem now is that Hollard has increased my excess from R3000 to R5000 and also increased my premium. I called in yesterday to query this, I was told a Team Leader will call me back. No one called me. I called in again to cancel my policy, I was then transferred to another consultant and then the call was cut off. I will call in again today to cancel my policy. I have been with Regent since 2014 and my last claim was in 2015.
