Yahoo Migration without "Collected Addresses" contacts

You harassed me about an "upgrade" to Yahoo till I mistakenly did it. You  assured me that everything would be the same, even my login credentials and email address. Then you only transferred a small amount of my contacts to the new Yahoo account! Most of my contacts were in what you called my "Collected Addresses" file and AI says that was a hidden file that you did not transfer as you promised! Even if AI is wrong and you did transfer that data, Yahoo says I should contact you and you tell me to contact Yahoo!

1.) I called your help desk who said I was no longer with you so they couldn't help

2.) I was told you and Yahoo had set up a specific Yahoo and Xfinity help desk to deal with data that failed to transfer during the migration. A Dedicated Migration Support Line, so I called them @ 866-764-7650. They were Yahoo agents who told me they could do nothing I needed to call Comcast/Xfinity CSA line

3.) I called Comcast Customer Security Assurance line at 888-565-4329 and the Comcast/Xfinity CSA agent said I had to call Yahoo at the Migration number who had sent me to them. Just like the Yahoo agent who assured me it was a Xfinity issue the Xfinity CSA agent assured me it was a Yahoo issue!!

Your solution to your significant error by loosing most of my address book just leads me in a circle!
