Pathetic car insurance policy

I opened my Absa insurance policy in Jan 2024, and Dec 2024 I got an email from Absa saying my premium has been reassessed and the old and premium indicated on the email is a triple of what I was paying and the new premium is a double (so inaccurate information, I don’t know how they can get that info wrong). I called Absa in December and one of the agents confirmed that it was a system error and will be sorted the first week of January as they can not do reassessments in December. I have been calling Absa since the first week of Jan and their systems are always down for reassessment. I then got an email mid Jan saying I can ignore the reassessment email, to my surprise I just got a debit order yesterday with the same about that was stated on the reassessment email. I called this morning and their systems are down again. How frustrating is this, and how can premium double when I have never claimed?
