Does anyone know how to get in contact with the NJ Division of Taxation (other than by email or online posting on their website)?

Have a refund (sourced from a few PTE/BAIT payments) that has been "in process" for well over a year and NJ DOT does not seem to answer the phone - they have not since COVID.  I will try the tax practitioner's hotline but I'm not expecting any better results.  Would consider NJ Taxpayer Advocates Service but I don't currently have an appeal.

Just seeing if others have had the same problem.  Thanks.
