Lack of Feedback and Communication

Since signing up with your company, I have never received a statement regarding how much I have paid your company since inception. I sent an email on the 11/03/2015 and only received a response on the 18/03/2015 with a statement reflecting that I should have been paying R480.70 whereas I signed up for R437.00 a month. I still have no clue how much I have paid your company and was never informed about this increase, which means when it's time to make a claim you will say that I haven't been paying the proper amount. Please cancel my policy with immediate effect and refund all the money I have paid your company urgently.
