Loss job, moved payment out

Help. I have kept in full contact with at&t, 2 lines plus plan. I moved my payment out. Loss just job 3 months ago. My payment was to be paid the 27th. They shut my phone off the 20th. Never have I been shut off. Isn't there anything they can do.  I'm in the middle of job search, I attempt to call at&t and I can't! I'm livid and tempted to say screw it. I did everything customer service told me to do.
