Cancelling my CCT Plan or Converting it to a Single Apps Plan?

Somehow I made a mistake in getting on a CCT plan for the entire year.  I already had a All Creative apps plan through another account and I don't want to be charged for two memberships/contracts.  I would like to see if its possible for an adminstrator to help cancel my CCT plan because there is a no way to do it on my end (no option(s) available).  I also want to see if a refund for at least January if not both could be credited because I had a license sitting around not being used for anything, because I had no idea I had subscribed to this thinking their was a biulling mistake with my ongoing plan on my other account. 

At the very least I would like to convert it to a single apps plan only and utilize PS as my sole application.  I've cancelled my current creative apps plan too.  Can I get some help with this please?
