Looking for Information On Whoever Owns This Phone Number

[DebitMe]

Hello, I run a localbitcoins business and over the last 2 years have become really close to a customer.  He now owes me $6800 and is not returning my calls or texts anymore, which is very unlike him.  Either way, I refuse to be out this money and am looking to anyone who has skills at tracking people through phone numbers.

He has used 2 phone numbers with me, and as of 3 weeks ago, was still using them, the numbers are...
417-396-1626
229-299-3062
He has told me his name is Jeff, and I am inclined to believe that since I have heard others call him that as well.

Any information that can be looked up by that information would be extremely helpful.

Thank you!
