Have recieved a few calls from this number over the last week. Comes up as Quality HM ENRG. But I was home today and picked up, no one would reply on the other end. So I have just placed my phone on automatic redial and it keeps calling them back and blocking there phone line..:). When they pick up I can hear them trying to disconnect the line but it takes them about a minute to do that. Then I hit automatic redial again. Will keep it going all day today...lol.
