I have received calls from this number; no one leaves a message. I have no business affiliation with anyone in Nebraska and do not have any outstanding debts. I have placed my number on the no call list a few years ago when I first got my number because of calls like this.
If you receive calls from 402-401-4531 or 1-866-767-3538, report it to the Consumer Financial Protection Bureau at consumerfinance.gov/complaint. The company is a debt collection firm called Levy & Associates, LLC, located at 4645 Executive Drive, Columbus, Ohio 43220. The company may call multiple times, and may or may not leave a message, but if you did not initiate business with them yourself, report them immediately to protect yourself and fellow consumers from this kind of harassment.
I keep getting (multiple times a week for the past month or so) calls from this number, if I answer, no one responds and they never leave a voice mail if I miss the call.
