This is a collection agency out of Iowa that uses many different phone numbers. When you block one they will use another. If they are contacting you track the calls on a detailed log and refer to a Collection Defense Attorney.
They are very annoying call 50 times a day from different numbers. Have the ability to leave more than one message per call? I spoke to them once and asked them to send information on the medical bill they were trying to collect on and they would not send me anything. I don't answer anymore but wish there was a way to go after them for the disrupting me at work and from 4am in the morning until 9pm at night
