Actually they dont give any contact info directly in the AOR, only at the end of the letter is the address and contact info written but also as i read it over again, they say:
we ask that you do not request a status report until AT LEAST 3 months have elapsed.....
"at least" that means that would be the earliest they MIGHT can tell you something, but doesnt mean by then they can tell you for sure, it can take longer! Basically just wait and let them contact you. It should be a good sign anyway if they dont request anything in 3-4 months and the visa should be issued soon, but if you dont hear anything in like 6 months (cause in my case they write to me it could take 7 months), i would ask for an status report.
