Every bill you can change when it comes due or gets withdrawn from your account. Folks are confusing that with someone who can’t budget and pay bills on time trying to get a grace period
No one is confusing anything. If you are broke enough to not be able to pay your bills on time, then getting your due date changed while easy to do, demands a requirement of being up to date to do so. And that obviously means paying the next bill cycle sooner than normal or paying your next bill plus a prorate of the days added on to get your chosen due date (which broke folks won't be able to do)
The conversation is about not being able to pay bills on time and being behind now. You can't just remove the variable of falling behind and act like we are just talking about the mechanism of changing your due date.
Everyone knows you can change the date. It's just a phone call. No company is changing the date if you are behind on payments. You have to be current. And the entire reason this is a discussion now is about people falling behind on their bills and not being current so clearly "these" people we are talking about can't do it. I'm not even talking about their budgeting or lack thereof. Just the function of changing itself.
