Some PPL don't fully understand how a 30 or 90 day cycle works, because its NOT a monthly service, and date never stays the same, so if your plan started on lets say the 19 of Aug, well it changes depending on month, as one month has 30 days while the other has 31, Feb has 28 or 29 on leap year, would be educational to know how this would work, especially those on low income
