unsolicited call to my cell. been spamming me for 3 days now

T-ey Called, I Ignored it... no message left.  I can only think that it's a call from someone reguarding something totally unnecessary and probably to the exact opposite of my benefit.
I've recieved 5 calls inbetween the hours of 11 a.m. and 2 p.m. none of which I recognize the number or have answered.  none of them have left messages, all of them different but two...
404-891-6835
617-960-9961
314-627-5604
312-878-5679

The same exact 4#'s called my phone back to back on yesterday.

In the past 24 hours I've received 8 calls from the following numbers:

650-204-3191 Unknown Name and V09011644320026
314-627-5604 CI Learning
312-878-5679 Classes Online
302-394-6827 Classes Careers
213-289-5542 Careers Institute

These are all scams who claim that I've filled out an online application and/or survey about online training.  I've also been plagued with spam emails from these same types of so called 'learning institutions' via my Yahoo account.

This number 314-627-5604 keeps calling my cell phone.
