If there's one thing I've learned after talking personally with literally thousands of bill-payers, including business owners, it's that the customer is seldom right when things go wrong. The customer usually wants to do whatever the hell they want to do and expect the corporation to maneuver things around and make exceptions to policies and procedures in order to satisfy the customer. Guess what? There's a lesson every sailor knows that many land dwellers would do well to live by. The biggest vessels move the slowest, so it's up to the smaller vessels to maneuver out of harms way. Whether it's Wells Fargo or Microsoft or the IRS or whatever business scenario you want to throw out there, you need to play by their rules to get what you want with the least amount of hassle or frustration. This doesn't mean they never make mistakes, they certainly do from time to time. However in the example stated above, sending one check to pay 5 different accounts...that's just asking for a "mistake" to happen. Next time, send 5 checks...even if they're all in the same envelope with each check noting the individual account information required by the company and 99.9% of the time the payments will be handled properly. This shouldn't be considered a criticism of the attempt, because it can't hurt to try something once, right? But to bitch about a huge corporation screwing up a payment to multiple accounts made on one check seems ridiculous to me. Hell, I'd be happy they hit 3 out of 5!!....If I were running the show there, I'd have applied the payment to the first account at the top of the list and caller 'er a day. And on a customer service note, you'll probably get the late charges credited right away by calling in and staying calm, explaining what happened and ask the rep you work with to move the payments to the right accounts and credit the late charges WITHOUT coming across as Mr. Right pointing the finger of blame at them or venting and you'll likely get everything you ask for, within reason.
