blocked out of email

My email has me blocked or shut off.  I was blocked out last week, got the code sent to my phone and was able to change my password and get back in.  Once in I noticed alot of strange replies from people I did not know, so I am assuming someone hacked in and sent alot of SPAM from my email.  This week it happened again and I could not get in with my password.  Now no codes I receive from my phone work at all and I got a message at one point that my account was closed.  This is an account I use for business and it is very important that I get back in.  Could someone PLEASE help me, I have filled out the forms, etc... and nothing.  Need help!!!!!  Also how is anyone to help me if this email does not work, I have listed an alternative in previous forms.
