Who called from 9794767000

Multiple phone calls  - one right after the other. I didn't answer because I didn't recognize the number. No messages left.

These people called trying to say they were with our phone provider and had the wrong (outdated) address for our company.  I don't know who they are but i'm not giving info about our company to anyone that can't get our address right.

Called 09/15/14 8:56 PM.  Caller ID, "SSI", tel. no. 979-476-7000.  Didn't answer--Obviously a scammer.

keep getting this call. all i get is a beep. today i called back, a recording answer and said for me to go to a website.

Calls continuously. Never leaves a voicemail.
