Incorrect Premium used to calculate Monthly Payback (AGAIN!)

My monthly Payback is being calculated using an incorrect premium amount. I spoke to maybe 6 or 7 different people at your call centers last week, related to some other issues, but I distinctly remember telling this to one of them, and yet, more than a week later, this is still not resolved. The lady I spoke to earlier now needs to log a new query to the IT team, and she hasn't found anything noted on the policy which would confirm they were actually informed about this issue. Your calls are recorded, not so? Surely someone can go back and listen to all those calls last week and then let me know why this hasn't been attended to. And at the same time, sort out the premium showing on the app before I need to have another fight with you people just trying to get back the correct Payback amount!
