Called my cell, I did not answer, left no message

Called....no message.

I recieved a phone call from this number, but they did not leave a message. However, when I tried calling them back, all I got was a " I'm sorry, but the person you have called does not have a voicemail box that has not been set up yet". I find this a little bit weird and unsettling. Because normally, if you try calling back a solicitor's phone number, it gives you options to be taken off their phone list, and not a message about their voicemail box not being set up yet.

Called but didn't leave message.
