Who called from 7183378859

Called my cell phone and hung up. then I called the number back from my home phone and the line has been busy for more than 3 hours

they called me AT 4.26 GOT SAME BUSY SIGNAL

Left a voicemail asking if I was interested to call them.

Got the same call as everyone else.  Asked "Is that the company name? carpet care?" and got the instant hang up.

I guess someone will have to try to schedule a fake appointment with them to get more info.  The number is of course always busy on call back.

Missed call. No message. Booo
