Who called from 7204524600

Same as others, the call came in on my husband's cell phone, which number we do not give out.  Rang twice, hung up.

Called my cell, rang once, then stopped.  Came here and read the comments; don't think I'll be calling them back.

Rang my cellphone once and then nothing.

Called my cell phone, rang twice and hung up. I didn't answer. Based upon the other comments it sounds like this is their modus operandi to do so and they count on people to call them back.

Rang my phone 3 p.m.; didn't answer it, no message.
