If you get an email or phone message telling you to call 1-888-634-9403 about your student loan (or any other loan/financial issue), do not call. These scammers will claim to help you with your loan but will require you to pay them upfront as a “service charge” (or similar). However, once they have received your money, they will do nothing. Even worse, any personal information you share with the scammers may in fact be sold to other scammers.
Note that if you call the number, the scammers will use the information on your caller ID for their scam. Therefore, do not call.
