I have been using a Yahoo alias with my primary Yahoo account. But I wanted to have that alias as the primary ID. So, I searched for any viable option to do this, on their help pages. Finally, I got this link, which made my search fruitful. If only I realised I was getting into trouble!
I followed the instructions there. Deleted the alias first and then tried to sign up with that alias. To my distress and frustration, the system told me the ID existed. To verify this, I sent mails to the deleted address and all of them returned undelivered, bearing the reason that the ID did not exist. I contacted Yahoo support. They tried to convince me that it is not possible to reuse a deleted ID. Further, the issue was escalated to their priority support and then to some other teams. Some people replied that I can reuse the deleted ID after six months, and some said I can never reuse it. I invited their attention to the above link, but they seemed to ignore it. Finally I shot a mail, asking them a clarification regarding the information available on the said link. And, this was the reply I got:
"The page in question is problematic because it appears to imply that the process is quick and easy. The reality is that it can take at least six months to free up a Yahoo! ID after it's been cancelled. I apologize that the page is misleading, and we will see to it that it is adjusted accordingly."
and this was another reply:
"This means that the system has received this ID as terminated, to date I have never seen a Yahoo! ID that has successfully been recycled. So you probably will never be able to re-register the YID. I do apologize for this inconvenience"
But what help is this information to me? Filed another request to make the ID available again, as I only followed their instructions and got into trouble. Headless people there! They might correct the information on their webpage, so I took a screenshot before that (see image).
