Ally Invest review: Book keeping error of my stock holdings

I own 700 shares of New Residential Pfd B (NRZ.B). On August 1, 22 company changed its name and symbol to Rithm Capital (RITM.B). It has now been 30 days and my account still shows old security and symbol. I cannot buy, sell or do any thing with old security because it is an invalid symbol. I have been in touch with customer support since Aug 10 and have spent several hours trying to get this corrected. No success to date and no promises of when it will be corrected. My last resort is to file complaint with FINRA as soon as my latest montly statement is available.
