Our AT&T email accounts have been hijacked and AT&T won't help!

We have had these email accounts over 24 years. Mine, my husband and our business account. They have been hijacked along with my  AT&T account (cable & internet). I was on the phone with Att From 11am to 3:30pm two weeks ago. They helped me get into two email accounts and my TV/Internet account. They said I would have to wait 1 month then  AT&T would send me a text with a link to get access to my husbands email. 

We use our email accounts to connect with Doctors, Finances, Claims that have been filed, our trips and airlines. We don't have access to very important information. This is serious.

Today I tried to log on to two email accounts and my  AT&T/Tv/Internet account and I am not able to. It says I have the wrong passwords again. I requested a link and the link came from [email scrubbed]. I checked online and found that this email address is spam and its not from  AT&T.

I have been extra careful with passwords and authentication and protecting our info. Ever since I called  AT&T support (over seas rep) about two years ago that same day I started to receive  AT&T spam texts and emails and phone calls. It's almost every day.

 AT&T said that my email accounts are free email accounts and that they never were attached to an  AT&T Account. NOT TRUE! When we rebuilt our home  AT&T assigned us a new  AT&T Account and our three emails were linked to this account. Now  AT&T said that we can only have one email linked to our  AT&T Account but that the website says you can have more but it won't allow me to link them.

I believe the hackers work for  AT&T.  

How is it possible that  AT&T can't do anything to help.  Please, I need help.
