Bonitas need to update their call centre

I really need some one to assist me in changing my plan, as I was never aware that my plan changed from last year to this year, if I knew that my plan does not even pay for basic dental I would of never stayed on that plan and paid R3K per month I mean its a ripoff. I want to please change the plan and I have already submitted documentation to change it. And I do not even want to hear of any penalties or any thing... It is Bonita's responsibility to inform the members of the changes every year and I WAS NOT informed and I want a plan that covers basic dental AT LEAST!!!! It is impossible to get hold of any one at Bonita's so please can this be dealt with as soon as possible, as I feel I need to be covered as soon as possible
