been getting these calls every work day for weeks. Called back on a different number and it says "thank you for calling the career advising center. If you have recently received a call from us, please stay on the line for information, including instructions to add your number on our Do Not Call registry." So I pressed 1 to enter my phone number on their DNC registry, and that was it. Not sure if it will work but at least there was an option to have a number taken off.
