I need A phone number for support.
That number is disconnected
Well that was a reply from 2014 - 8 years ago. Still, that is the current number, but perhaps you're not calling from the USA? There is a different number for each country, which is why you should go to Adobe's support pages for the current number https://helpx.adobe.com/contact/phone.html
why is this number posted in a forum and not under support?
Because they SAY they provide customers w good service. But they do NOT. As with most companies? That's a lie.
