How long has a simple DoS FOIA request taken for you?

Hey,

Put in a request around two months ago. Case says "Assigned for processing" and the estimated date has come and gone.

I understand from reading online there is a backlog, does anyone have any information on how long it has taken for them to get back?

Also what is the best way to contact them to get some info on timelines? Is there a phone line or an email where they are responsive?

Thank you
