Another unwanted call from this Conejo Valley area VOIP number arrived today, less than 1 month since the last unwanted call on Sept. 26. When the answering machine picked up, the caller responded with dead silence. This is the tactic of robocallers (unlawful telemarketers) who continuously troll the phone lines, desperately seeking gullible schmucks to victimize. The perpetrator is identified as a scam HVAC contractor (probably unlicensed). Also today, another serial scam HVAC contractor -- Quality Air -- unlawfully phoned again from (909) 245-0598, a Crestline VOIP number. Could Quality Air be using VOIP lines at both (805) 244-2268 and (909) 245-0598 to conduct its illegal activities? Inquiring minds want to know. Whether it's air duct cleaning, HVAC service home improvements, computer repairs, credit cards, vacation giveaways, fake charities, or the IRS, A SCAM IS A SCAM IS A SCAM!
