Complaints about Phone Numbers385-388-####

Got a few calls from out of state numbers (FL, NY)

got a call from a "private number" stating that they were a "legal courier" and if I did not meet them at my home or place of business tomorrow, the "case would proceed without my cooperation" said if I needed to reschedule, to call the office that was associated with this debt...833-678-1410. When I called, they do not identify themselves, only say all representatives are busy, leave your name, case # and phone number and someone will call back. Now I look at my call protect on my phone, and 385-388-8703, has attempted to call me back seven times, but was blocked. I am certain that these calls are all related....scammers I am sure!
