It just ain't happening no matter which help or advice I seek. Thus causing me absolutely bonkers from pure frusturation at the lack of help and support needed for all of us who can't acces anything anymore...not to mention the total confusion of remebering all of the diff emails and passwords..passwords.. recovery numbers etc. It will make one lose their marbles completely. I've spent over 2 months at 10 + hours a day trying to resolve this problem ..... fighting this huge issue and to no avail...can't access a damn thing . even tho I am certified and verified thru the nose!! I'm definitely ceritiiable in something as of now. A,d need a vacation. I've tried everything under the sun short of cal)ing the national guards...what a nightmare this is.....anyone have advise or answers? I won't hold my breath so no worries there..lol.
