Academic Support Center: Is my mom about to be scammed?

Hi everyone, my mom was on PSLF and only needed 4 more payments to complete. I'm not really sure how any of this works at all, but she called Mohela and was told to call: 1-888-272-5543

The representative said that Mohela wasn't handling it, these people were.

Now she's concerned because that phone number and the website aren't matching? Has anybody encountered this?
