Rotech Healthcare

For over a year I have been having billing issues with this company. Each time they assure me it was an oversight in accounting and we were straight. A few months later I received a new bill. the last one I received I went to the local office and sat with an account rep. she called the accounting office and I was assured that if I paid the bill (2nd one) that all would be square. Now I have received another bill. When does this end? Appears they can't get out of their on way. Sorry I got mixed up with with this company. I sure won't make this mistake again and I will try to convince my associates to not make the same mistake.
