DR JoseSPiano - you need to hire a shrew/harpie to do your Accounts Receivable for you! 
Alas, A/R has nothing to do with this situation. At least not on my end. What I am dealing with is a night manager at the hotel in Florida that somehow improperly billed and charged me for my whole two-week stay even though it was clearly listed as "Bill To Company". -Even though when I checked out, my final bill (at that time) had a zero balance - I didn't even incur any charges for incidentals during my stay. Apparently something happened during the final part of the billing process
after I had checked out, and since it can take a few days for charges to be fully processed, well... I had a very rude awakening this morning when I went to check my bank account balance. Very rude. And since I had also written my rent check last week and made a couple of other payments, well... And since I'm heading down to Florida Wednesday morning, well... Lots and lots of phone calls over the past few hours.
