Who called from 4122007961

They are claiming to be a mediator group for outstanding loans. They are threatening legal action on a loan i never had.

Criminals masquerading as debt collectors attempt to extort money from people by scaring you into believing that you will be criminally charged (they use the bad check or hot check claim a lot) and go to jail, lose your driver’s license, have wages garnished without actually being sued or going to court, be sued, and a variety of other variations on this, all for an alleged or nonexistent debt.  One of the tricks they use is to call your family, friends, neighbors and/or places of employment (past or present or both) to create panic and embarrassment so that their intended victim calls them and they can scare that person into paying their extortion money.  They will use the words “Mediator”, “Arbitrator”, or “Law Office” to make you believe that they are something other than a debt collector want-a-be and that they don’t have to follow Federal and State collection laws.  They do have to follow those laws, but they won’t.  They also use the “process server” ruse who calls and claims he is going to serve you, but then says you could avoid it by calling another number where they will ask for money to “make it go away” (this is actually the same place, they work in teams, one pretending to be the server, and the other usually pretends to be a lawyer).  Process servers do not ever call ahead so that you can dodge them.  Process servers get paid to serve papers, nothing else.

Is this a scam for money?  They sound professional  and have extensions for their 888 number. I was accused of owing money on a loan that i never had.

They also call my brother 10 or more times a day. How would they get his cell number?

Yes, and if you read my post, I think pretty much everything is explained.  If there is something that isn't in there, then using the provided links should answer any questions you have.  Calling your State Attorney General's Office will get you some quick free advice.
