I received the exact same message as above on 7/10/2019: "Yes this is Shirley Bates and I'm calling in reference to your federal student loan. I need we need to discuss your repayment options with some new changes that have taken effect recently so if you could be sure to give me a call back my number is 866-298-1551 and I'm gonna give you a reference number if you would please have this handy when you call back it just makes things a lot easier. Your reference number is 110003. Thank you." I do have loans and called back, and the phone kept hanging up. I should have realized it was a scam and checked on here from the beginning. LIVE & LEARN!!
I got that same message from that same number on 6/18. Just got a very similar message from "Stephanie Lawrence," with a reference number of 770009 - from 866-817-5665
SCAM. Very convincing business/office sounding voice message though. Don't be fooled. Everyone is given the same reference # 110003. NO loan holder or name is asked for in voice message just generic except leaving same phony ref #.
