Who called from 7373006338

An interactive robo introducing itself as Sandra Keller but with no company name mentioned.  It is looking for the owner regarding a "big growth opportunity".  It's interactive, have fun with it.
Caller ID says ACCT SVCS.

Just blocked it, called me twice this week and left no message.

Just received a call from this Sandra Keller wanting to speak to the business owner.  I immediately said NOT interested.  SHE or "IT" said ARE you the business owner, I said you called a family business and HUNG up.

called didn't say anything when I answered.  Don't know what call type it is as they didn't speak or have a recording.

I receive calls but no vmail's. Blocked the #.
