Late Fees being charged!!!

They do mail bills as soon as they are generated. They can't mail them any sooner than that. If they are taking too long to get to you, that is the US Mail service. As you have already discovered, your bill is available online as soon as it is generated, there is no reason to wait for the mailed copy. You might want to consider paying electronically, too. Not only would you avoid further late fees, paying by check through the mail is one of the least secure ways to pay. I'm not sure why you were under the impression you would get a discount for combining your wireless and Directv bills, there is no discount I know of. If anything, combining your bills only leads to more issues. 

@B17635 said: “ I have to print this out and mail it before I even receive the bill to avoid late fees.“

If you are “printing it out,” you are receiving the bill. I’m not sure what the issue is. 

This has come up a few times.  Realistically if you mail a check, someone has to manually process the check, and you hope they credit the right account.  It’s inefficient and a waste of time and manpower.  Both yours and at&t’s  

    It’s 2019, let’s get with it!  Save a tree and assure your bill is paid accurately and on time.  You can still get and file the paper bill if you want.  

Carriers have all shortened the time between when bill is generated and when it’s due.  The standard is 21/22 days, Verizon being the last to conform last year.   

Carriers bill in a way to make sure they get paid for your current cycle, during that cycle.

ATT does mail your bill as soon as it is generated, the same time you get the email notice that the bill is ready, so unless you have proof ATT is mailing your bill late, your problem is the US Postal Service. If that is the case, you will likely have the same issue with Verizon wireless because they follow the same billing dates as ATT. You can’t compare internet service or home phone billing with wireless. The internet/home phone bill gives you more time to pay, it is the same on ATT.

I just don’t understand why anyone is reluctant to pay electronically. I hope you realize that everyone you write a check to, including ATT, processes that check electronically. You may not be paying electronically but your bank account is. Good luck with Verizon.

One of my clients (older lady) insists on using checks for everything.  Her checking account was hacked twice last year.   The bank finally got her set up with electronic payments and the police gave her a safety plan.   The weaknesses are unsecured email,  bills and checks in the mail.
