Missing form 1098 from new lender

My mortgage got sold to a terrible lender in September 2023, and I only received the form 1098 from the original lender but none from the new lender. Both the mortgage interest and the property tax numbers are  missing/inaccurate. The new lender's website also doesn't show any available 1098 and their customer service is unreachable (hence, terrible lenders). They already made plenty mistakes on my loan, now I am even not able to request tax documents from them. What do I do and how can I file the tax for 2023?
