How do I DEACTIVATE Elements 13???

Question

NOWHERE on the Adobe website can I find instructions for doing this, even though I'm told I must if I want a refund within the 30 day return period. I just keep getting bounced in a circle of links. I'm SOOOOOOOOOOO Frustrated!
I bought Elements 13 after trying for days to get a trial version (which did not work, and trying to make it work ended my trial, which still makes no sense to me). I was told that if I bought it and did not want it, I could get a full refund within 30 days.
After I finally bought it, when I did not get any other options from Support, and waited a couple of days for a forum post to be answered, then I got an email from someone in support, saying they had given me a serial number, good for 30 days. So now I have TWO registered versions of PSE 13.
I bought it (and also got it for free) and do not like it and want a refund, but have read here that I first need to de-activate it and then uninstall it. I've looked everywhere I can think of for a way to de-activate it and cannot find out how. I keep going to suggested links for more information on the Adobe website, and get bounced to pages where I've already been.
I was directed to get help in 'chat'; wrote a detailed description of the problem there, and clicked on the 'start chat' button. Nothing. No response or change of any kind. The page just sat there.
So I went to the forums to find one that fit my problem. Apparently Adobe does not think deactivation and/or returns deserves much attention, since there does not seem to be a proper forum for discussing them. This looked like the best one.
This is just another in a series of amazingly frustrating experiences in the last two weeks with Adobe. All of you in support have been as friendly and helpful as I could hope for, but your website has not been helpful at all!!!
Please help me to deactivate Photoshop Elements 13, and tell me the steps needed to get a refund. Yes, I can call on the phone tomorrow, but that has not gone very well, either. When I bought the serial number, I was told, because I very specifically asked about it, that a return would be easy. HA!

Answer 1

Well, with no help from the Adobe website, I found the answer (I think) in another forum query. It said that, to deactivate, I need to open a project in 13, click on the Help button, and sign out. I want to make sure: Is that all that is needed to deactivate? (If so, how hard would it be for Adobe to put this somewhere easy to find in their FAQ?)
Then, the next step before getting a refund is to uninstall, correct? And the final step is to get a refund by somehow getting in touch with someone.
My question now is, what about the two different serial numbers? Someone in support went ahead and activated the number they gave me, so I currently have two. The free one is supposed to end on December 12. Do I just ignore it?
