I've had this problem, too and submitted a ticket, but it seems to have disappeared. Took out all my mods, blah blah blah. Worked for a test Sim. Put all my mods back in, still worked for my test Sim. Went to play a saved household, they can't pay bills. Moved them to a new lot, can't pay bills. Traveled, can't pay bills. Used a library version of the same family, and they can pay bills on a different lot and the saved lot I moved the original Sims out from.
They go through the animation, whether by phone, computer or mailbox, but the money never gets subtracted from household lots. The repo guy showed up, too, after having utilities shut off with the original Sims. The game is not playable. This is 100% a game-breaking bug. Wondering if I need to sell the business to get the bills to work? Whatever the problem, it's with this pack. Of course.
