I receive calls from this number at least 5 times daily.  I do not have any business with this company and it is harassment.

It is NationStar (or a proxy for them) calling.
I, too , was "sold-off" to NationStar last January.  It has been nothing but phone call hell ever since.

They're a menace and, in my opinion, borderline crooks.

I suggest sending a letter (or twenty) to their corporate office/mailing address (they only give a Post Office Address--probably out of fear that one of their "customers" is going to walk in and "go Postal" on them) requesting that all communication with them take place through the U.S. Mail and further request that the phone calls stop.

When the calls don't stop (and they won't), then it's time to file a formal complaint with authorities.

My loan also was sold. I owe 30K on a 100K plus house so why the hell First Horizon sold the loan I cannot figure. I did change all my accounts to a credit union because they did that.m I used to be able to pay at the local branch.
Now I have been tring to set up direct pay with Nationstar for 4 months with no sucess. they want me to pay Wells FArgo 15$ a month to make a 450$ payment/ Yeh, go blow.
I have gotten 27 calls from Champion Mtg according to my phone id. As late as 10pm as early as 6:30 am over the weekend and 3 of them on Sunday. I just spoke with an agent at Nationstar about my account and she said she had never heard of Champion MTG. I will paying these slums off the first of the year. what a crappy outfit. Have never read anything but negative about them. No wonder theres so many foreclosures.

We've been getting numerous calls here at my business from Nstar Champion, several per day for the past several weeks. Caller ID shows up as Nstar Campion, 469-549-2000. I called the number back, got an operator and requested customer service to remove our number. After I gave them our number to remove, the rep looked it up and it turns out they were looking for a former employee who left here several years ago. I told him that I didn't know how to contact the individual and that they needed to stop calling us. We'll see what happens...

yep.some automated call that calls my cell 2x every day
maybe got my number from a response to someone interested in a item for sale on craigslist or off a job board like career builder
