aligning mutiple owned accounts billing date and durations

how do you fix multiple owned accounts duration dates when they differ ,,to pay on the same date and have the same expectancey date when reaccuring billing makes it appear as if the next pay is behind when you havent even began the next months experience ....should i just cancel both then start brand new?...ive tried this before and the assistant agent at the time was stuck on pushing the late pay bill when it hadnt even been experienced yet and theres not an option in help to deal with the particular details for aligning multiple owned accounts to pay and expire on the same date expectancey---

and or could there be a one step page for aligning multiple accounts by adding the accounts details on that page to restart each on the same date of pay so that it aligns both to expire on the same dates hints fixing the billing to occure at the same date closer to your already set income dates --

and hints discarding unexperienced late pay bill
