-I was told wait 3 months
-if you paid with CC online you should see a credit to your CC. Sometimes it is less than $200 (not much but like 197.37 or something crazy like that) no idea why, never happened to me but heard about it when i was researching my refund. just in case you want to search your statements, search 200.00 but also search ATF or something
-call them like you would checking on the status ( (304) 616-4500 ) and whoever picks up just say you have a question about your refund. they may ask if its been more than 90d, but usually they just transfer you to one guy, Scott i think it is (you can ask for him by name). He's super helpful, but hardly answers the phone so prepare to leave a message with al the info and play phone tag. Even his direct line gets intercepted by the normal people.
-******SUPER IMPORTANT PERSONAL TIP********** make sure you check ALL your CC statements. I used an obscure one that i never use, and thought i didn't get my refund (cause i did like 2 or 3 form 1s that month, but this one rejection was paid with some other CC) so Scott and i were going through all the hassles for me to find out that i didn't see the refund.
hope that helps
