Also very poor. I get these statements not long after visiting the Dr. and they note already "Your account is seriously past due. Please remit payment as soon as possible."
They've done this to me before too, turning me into collections before I could get the payment in and then saying there wasn't anything they could do about it. I work odd hours and it was difficult to find a time in their hours to call in. This time I tried to pay online (which they don't provide a web address on the bill they've sent). I tried setting up an account and it came back to tell me online billing is not supported by my provider. I went to the questions and comments section for billing and to leave a question about it, but by selecting to leave a "questions, comments, and complaints for billing" it redirects you to a page with only a phone number.
Surprise surprise.
