AT&T ARIN Contact

I have a few old netblocks that were allocated to my company back in the early 2010s that our security vendor is requiring us to either secure or remove from being registered to us. I’ve been unable to reach anyone at, and the number listed isn’t connected anymore.

does anyone have some contact info at ATT/Bell for getting these records corrected?
