Fuck AEP. I've had so many issues with those fucks. Regarding the voucher thing, I had an issue with that too.
I tried to get my mom to vouch for me when I moved into my apartment, but she recently divorced from my dad, kept the house, and since they had to change the name on the account the only way they could change it was cancel the old account (that had been active for 27 years back when they weren't even called AEP) and they denied my voucher request because her account was too new. Fucking BS.
