Business ProfileforbiBerk, by Berkshire Hathaway

In July 2023, I opened a small business workman's comp and professional liability policies with Biberk. My agency paid the policy as part of a contingency agreement working with my LLC. My contract and partnership ended in February 2024, so therefore I did not need the policies. As of April 2024 I have gotten repeated messages, emails, threatening notices from Biberks asking to send my payroll information, tax information and a number of high confidential materials to them. Today, I attempted to comply with this audit that seems to have not rhyme or reason (as I am no longer a policy holder), and I was told by a representative that 1. This is standard everyone gets audited when their policy ends 2. I could speak to and be transferred to an auditor (later was told they are not on today 3. Email my materials to premiumaudit@biberk. When I told her the portal/platform is not working she said it must be down today. However, on a previous call she told me log on and use the portal. I expressed how sensitive this material is and that emailing an unsecured email inbox makes me uncomfortable. I was told that the "audit" team would call me on June 24th? This is so confusing and unsettling. Why do we need to send personal income tax, payroll information and personal information after a policy ending with no outstanding balance? I would like help with having this company remove my name/contact from their list and to not reach out to me with escalated threatening language. The cost for the policies were quoted and paid upon with no issue since July 2023-May 2024. WHY now ask for all this information? How do I know how this will be used or stored?
