just got off the phone with a CG rep. they took a filter for me for all online checks that were uncashed after two years and found close to $300 so far. all have been stop payment and recredited to my account. interesting little feature and i had no idea they could do that. this cannot be done via online chat.
this is for online checks - which are debited from your account upon issuance - versus paper checks written by hand which are debited when they are presented.
