One of my loans was converted without my permission which caused it to not be one of the ones halted. I was unaware and didn't make payments for a year, didn't get notices, and when I finally realized they reported to my credit. Went from 830 to 600 instantly.
I was moved from Great Lakes to Nelnet a couple years ago, and then almost immediately transferred to MOHELA.
It's astounding how shitty MOHELA is. It's almost impressive. Literally every single aspect of the experience is godawful. The only way it could be worse is if they actively tried making it worse, and even then I think they'd probably accidentally improve a few things.
Great Lakes was actually pretty decent, too, in-so-far as any student loan servicer could be considered "decent". I never had any issues with them, and they made it relatively easy to manage, relatively low bullshit. Compared to the others, they were the least-terrible.
I am loathe to praise any entity benefitting from student loans, but I will say that Great Lakes was competent. The website functioned, they had [mostly] enough customer service people, their customer service people could answer your questions, and they billed you the correct amount at predictable intervals.
It's a sad bar, but it's more than MOHELA can manage. Godspeed, friend.
