Guess who has a corrected statement on the way

After a series of phone calls, an email and a fax yesterday our account was “reviewed” by “Moe” of the three stooges and she blames it all on “Curly” aka: the insurance gal. Her story is they apply payments taken in on a office visit day to that day and it is held in an “insurance bucket” until after insurance pays and then is suppose to be applied to the remainder of that balance after insurance has paid.
Only because dh is at 100% payment with BC the Curly never went in to move the payments out of the insurance bucket. When I asked then why was the one payment partially credited she said “oh she caught that one and put it on the bill that was from before insurance covered 100%” When I asked why just partial when that part was over $600 and there was $160.37 on that payment. She said because the remaining amount had been applied to a smaller “leftover” that paid all but $.80 of that. When I asked what statement that smaller bill was on, she said the one she was mailing me today. This is from January folks, yet it is just now showing up on a statement AFTER 4 months of inquires.
Lucky for her I was familiar with the $5.34 amount because it had been on the BC statement ever since January, as a balance due to the doctor, it simply had never shown up on the statements from the doctor. So I know it is a legit amount, just VERY sloppy bookkeeping.
She did make the mistake of trying to talk down to me in the very beginning by saying “you just need to know how bookkeeping works and you would see this is all normal.”
I stopped her right there and informed her that not only did I understand how bookkeeping works but I have a degree in it ( which I do) and their system is on the creative side of getting in legal trouble and would suggest if they were going to continue to use their “insurance bucket” system they jolly well better start showing that on their statements before someone ends up on the wrong side of the law.
She changed her attitude real fast.
Later on in the conversation she suggested it would have all worked out if I had just paid the bill in full and then their system would have flagged it. I informed her I am not in the habit of knowingly over paying a bill and they shouldn’t be in the habit of expecting customers to because of their sloppy bookkeeping. I also told her they were not getting a single penny more until I get a correct statement with the payments ALL applied to the balance immediately. Then once I have the correct statement I will pay them in full on May 27, 2015, but only if I get the statement prior to the 20th. It is being mailed today, supposedly.
They were also notified I will expect a paid in full receipt at point of payment. She thinks I am mailing it to her, nope I am taking it to the office, demanding a face to face and an immediate receipt. No receipt, no payment.
I am still filing a complaint with BBB. There system is beyond being legit. I wonder how many people they convince to over pay a year and either don’t refund them the difference or drag their feet in doing so.
