A maze of websites but no wireless bill

I spend over an hour every month hunting for my wireless bill. I have yet to find it on-line.

I am sent to all these websites told to click on My ATT and  choose wireless. Ultimately I end up at my U- Verse account.

If I do not pay the wireless bill on time ATT disconnects my service. Then charges a $50 fee to turn the service back on and another $50 reactivation fee

Please, can someone tell me how to find my wireless bill? 

Thank you.
