Bad Service

Since March 2020 I'm battling to get my account sorted out - they never answer even if you phone them they tell u a different story every time (o your account is fixed or sorry it was fixed but the deduct the wrong amount or sorry we will look at it and rectify it - same story every month) paying different amounts every month where I should be paying R799 + R70 for insurance - I just need my account to be rectified for once and all and paying the correct premium is that so difficult to do?
