Just BAD Service

I am just at a loss words. Called in on 24 July 25 to remove a vehicle and add a new one. on 25 July, a pro-rata debit ran. I call in on 29 July to advise that excess etc. needs to be adjusted as the consultant failed to do that, on 30 July a pro-rata debit runs. on 7 Aug i call to add a vehicle and the same evening a pro-rata debit runs. My DO date is 20th every month, by my first call, a full premium was collected already. This means the pro-rata amounts post that should have been offset against a full premium. That did not happen. This morning I wake up to a DO of R8640.00 which is not my monthly premium. Call in to the call centre, they unable to explain. I have queried the pro-rata amounts multiple times and every time someone was to call and no one did. A DO of almost double my premium post pro-rata amounts. I am just hopeless right now.
