I haven't responded to most of the calls, but I did have work of various sorts done on my house and the number of calls just seems to keep increasing, even though it has been, at least, three years since any major work was done. I wonder what these fools hope to achieve by harassing people. The single ring isn't really as annoying as having to listen to 3 or 4 rings and see no ID on phone or call log and dead air on voice mail.
Guessing you are also in the 562 area code and probably had some sort of work done either on a home or apt. your name and number have probably been sold, as I am pretty certain mine has been. There are several other people that keep reporting the same numbers also. I have found that Nomo**** hasn't worked too well for auto-dialed calls, but seems very effective for Robo calls.
Yes I'm 562. My calls were a result of a home business, which are all public record. But I really made things worse when I let loose on one of these idiots. He said he would make sure I was on every list possible. Boy he wasn't kidding. Nomo*** has been very effective for me, but the single ring is annoying.
