Trial cancellation

I've been trying to cancel my trail of Photoshop all weekend and it looks like I have two Adobe Id's but the trial doesn't appear under My Plans for either one. I've tried going through the help messenger a few times through both Id's but never recieved a reply. I've also tried merging the accounts with my Facebook account but no luck there either-afraid I'm going to miss my free cancellation window- any how-to cancel advice?
