how much is the expansion of the creativecloud membership tofrom 1 computer to 2?

Hello,

I can't connect to the support line, they put me on standby for 40-45 minutes everytime I try... Chat doesn't work, I don't know any email address. The only thing remaining is the forum.

So I would like to know if someone here knows how much costs the expansion of a creative cloud membership from 1 computer to 2. I'm in Italy, I don't know if it's relevant.

Or if someone knows an email for the support, please tell me.

Thank you in advance.
