Error when tryint to merge Fotolia account with Adobe Stock

I can't transfer Fotolia account to Adobe Stock.

When I try to do. it's show this: "Please contact our customer service team through this form for assistance." or: "The selected account is already being used". 

I deleted my old account on Adobe Stock recently, now I create a new one, I suppose this could be a problem, but I still got emails of my sold files, but I do not have an access to my gallery. What should I do now? Thanks for your kind help!
