Bad Service after so MANY years

I am not very happy with the service I am receiving lately my insurance (Hollard) have decided that my policy plan WILL fall away and that after 10+ years being with them the have added me on a new plan that benefit them more with double the excess and a higher premium, my broker tried to negotiate with Hollard but with no luck, how is a R4000 excess and then another R3000 for a driver younger than 25, How can they just move me to a more convenient policy to suit them. I can not believe that they chase away their years long customers like this? What is happening to customer service these days every thing is just about money so for me it's bye bye Hollard
