...unless I can contact them (sorry I don't have the letter at work with me). But there are 3 dates listed: the date of the letter, and what looks like two deadline dates. The first deadline is June 25 and the second is May 25, which is one day after the date of the letter (5/24).
Note: AES used my old address and the Post Office so kindly (lol) forwarded it to my current home.
Do I have a case? Also, I'm a newbie, so if anyone can point me in the direction of anything AES or Pennsylvania HEAA related, I would appreciate it.
