I had a pretty similar experience with skype. I lost access to my connected email account and was essentially locked out of my account forever - repeated emails to support were met with silence, alas! Then I connected my facebook account to use skype instead... then they discontinued support for that. Now it's got to a point where attempting to create a new account on the OSX desktop version just shows an error screen every time, so I'm stuck unable to use skype forever. I've moved on to other, better solutions, naturally :)
