Still having problems with billing. I paid the co-pay with a credit card. Usually, I pay with a credit card in the office, and by check if by mail. This way, I have an independent source for confirmation of payment. I got a bill in June, and the staff told me that it would be handled. I got another one in July, and I wrote a letter to them and sent it certified mail. A month later, it was returned because they would not sign for it. I also got another bill from them. I wrote a second letter showing that they refused the first letter and outlining the problems once again (with backup documents), and sent it regular mail and certified mail. I also told them that I would not respond to any further bills. If they put me in collection, I have enough evidence to show that I paid. Damaj really needs to get his administration up to speed because it is really unprofessional and an embarrassment.
