I am desperate to talk to someone to find out why I have been charged after signing up for a plan and then cancelling in the allowed time. How do I speak to someone?
there are 3 ways to contact adobe; chat, phone and twitter:
use a browser that allows popups and cookies
and click here, https://helpx.adobe.com/contact.html?rghtup=autoOpen
in the chat field (lower right), type AGENT
be patient, it can take quite a while to reach a human.
p.s. if you're contacted by anyone (via email or private message), it's much more likely to be a scammer than an adobe representative. ie, double check for an employee badge if contacted in the forums and look for an adobe.com domain in the email address if you click reply to an email. then check again and be very suspicious. any other method of contacting (or offering to contact you) is almost certainly a scam, https://community.adobe.com/t5/using-the-community-discussions/staying-safe-in-the-adobe-support-com...
Click on a phone?
The chat works fine. Read what has been written. Use a different browser or a different device. And you still can use twitter. It's not a stock reply (even that @kglad probably gives this advice 30 times per day) but it's the solution to contact customer service.
I use a similar "stock" answer. I'm answering about half as many questions than @kglad ! So there are more users wanting to contact Adobe customer care. However, there are thousands of users getting to customer care without our help. And there are millions of users not needing customer care.
Contacting customer care worked until now on every computer meeting @kglad 's requirements. Those who don't get through have misconfigured their browser. Therefore the tipp, to use a different browser or a different computer.
the stock reply is still correct. if you have a problem with chat, it's most likely your failure to use a compliant browser though it's also possible you're in a country that affects your ability to interact with adobe.
if the former, using a mobile browser is usually successful.
the phone issue, i'd not heard before so either:
try phone again
try chat again
In your browser, use the link, that was given to you. Be sure to be signed in to your Adobe account.
you're not the only person to have adobe billing issues, but you're one of the few (if any) that seems unable to connect with adobe and rectify the problem.
be wary of unofficial contacts.
