Your DOFD is different than when the collection agency opened the accounts. Your DOFD on those accounts appear to be 2013 & 2014.
I've read that AT&T pulls their collections back every 6 months and gives them to a new collection agency. Some people have had luck watching for the collection to be removed around that time then calling AT&T directly and paying off the account before it gets transferred again.
