Distrustful employers lying for commission

I purchased a VW Up beginning April 2023, my broker quoted the new payment and all sorted with my insurance. Then on 6 June Shani Du Plessis phones to tell me my insurance is flagged, underquoted and needs to be reloaded to rectify, however, Outsurance will carry the loss and my premium remains the same. That night I receive an email of an increased amount, also on my app adjusted, I contacted my broker and he immediately investigated. According to an SMS he received I enquired about my policy and he was furious as she was not allowed to contact his clients. The matter was investigated according to my broker and HR at Outsurance will sort the matter, refund the pro-rata deduction and rectify the premium as it was. Till date no feedback, not even a SMS received. I lost my trust in my broker and most of all Outsurance.
