Who called from 3022615532

Received this call. Didn't answer it. Would like to know whom it is.

I recieve this call about 4 times a week. A male voice says to call another number.

Calls endlessly 2 or 3 times a day

This number is linked to Sallie Mae.

Recieve calls from 1-302-261-5532. Don't know who they are as they never identify themselves, but they call several time a week. It begins with "Thank you for holding, please wait for the next aviliable representative." I'm like excuse me, you called me! You don't call me and then put me on hold. I've looked on several other sites, says it's some kind of scam.
