Misleading and disappointing service

Took out car insurance in April 2019; was advised by Outsurance consultant that after 3 months I could call to get a better premium; as my premium was very high. Downloaded the app and noticed a detail was incorrectly recorded by Outsurance (not shown on the policy sent by email). After 3 months I called to rectify mistake made on Outsurance side and get a better premium; was told that my premium would INCREASE because of incorrect detail recorded BY Outsurance AND that I would be charged a FEE for the mistake made by Outsurance, I was also told that premiums are only reviewed yearly (and my premium would therefore not change). How unprofessional and misleading! Took the issue to management and they said they could do NOTHING about it. Disappointed and shopping around for better premiums and BETTER service.
