Adobe didn't sell it to you, since it is discontinued, finished, out of support. You will need to contact the seller for a refund.
did you purchase your product from these firms like Amazon? If yes, this is not a serial number, only a code with which you can request a serial number from Adobe. Please have a look at http://helpx.adobe.com/x-productkb/global/find-serial-number.html. (Start here: How did you purchase your product?)
The following part, so I just see at least, ceased to exist on my Adobe website, everything takes place in the link from above. I leave it as an info yet, it might still fit for you. For this purpose, please click your way through to your Adobe Store and find the button "Get Serial Number". Fill in the form and after a while you will get the real serial number.
What concerns a phone number: you can have a look there: Adobe Connect Help/Adobe Connect Support phone numbers
