I have gotten a letter from NCO requesting income info for my student loan. I provided them with the info requested and the held a "hearing" which stated that it would not cause financial hardship to garnish 15% of my disposable income; however, the amount they have as my monthly income in not even close to what I make. I only bring home $580 two times per month and have 3 children in my home. When I called them to report that my income had been calculated incorrectly, I was treated very rudely. I offered to set up an alternate payment arrangement with no success.
