Called my cell . . . left no message.  From California?

Received call today at 7:17 p.m. on my cell phone - No name came up.  Did not leave message

It is a company called Hey Cosmo. It appears to be some sort of message delivery service. When I called back it said press a button to recieve a text message from Sprint, and then gave 3 other button options for different services, none of which were to connect me to a live person to have them remove my number from their database. I reported them to the national do not call registry.

I called back, it's a telemarketing company for some astrology record.

No voicemail was left.

Called me today, phone rang for less than a full ring and hung up.

It said something about cosmos

I've received three calls from this number and no voicemails are left.  Has anyone tried calling it back?

I don't know anyone at this number.
