Called, left no message

Hang-up calls with no message.

Virus injection. Changed settings for my cell

This recorded message telling me how to pay my student loan debt and I don't have any student loan debt at all.
It's very annoying

I have called them back numerous times. Each time I spoke with someone they claimed I had a student loan that was outstanding. I barely graduated from high school and that is as far as I got. So exactly what student loan. I'm about to retire so there a little late if I did get a loan. They claimed that they would take me off there list of calls. Apparently that hasn't happened. They keep calling from different numbers.
