Who called from 3012520215

Got a call but didn't answer. no message left.

Got a call from this number about 37 minutes ago, called back and it said caller was unavailable.

I also got a call on my mobile from this number, called back and also got automated message that it was unavailable.

Automated female voice  said "Hello Hello. Are you there? Ok have a nice day." 301 252-0215 These types of calls are annoying.

Second time in 6 months that this Blast Dialer has hit my, and my Wife's, cell phones within 30 seconds of each other (Numbers are 82 apart.)

Direct Buy is the company.  Very clever taped message interacting with you asking Yes or No questions.  As soon as you answer "no", it hangs up.

All reported to DoNotCall Folks, but with no apparent result.
