Poor Service

I requested my policy to be re-activated due to an error on the bank side, I had to go through the entire process of underwriting the policy again and then my premium was R248.55, later this afternoon the same consultant called and said OOPS my mistake i didnt underwrite the policy correctly and your premium will go up!!!!!! I told him this was unacceptable and want to speak to a manager but no one has called me back as yet.....Needless to say this is the same consultant that assist me previously. Please can someone assist me urgently!!!!!
