Have paid this debt once to Sequestsol. Then it stayed on my credit report. No notice of paid bill. Then they said southeastern physician had original bill. Called them they have no record of it now last week this company called. I tried for several days. Keep getting same automatic message. Operator 000is not available leave message. I do and no call backs. I am fed up and I am going to report them to bbb. Problem still not solved. I would give them '100 but don't have that option.
