JS Plumbing & Rooter Service, Inc

I am in need of a plumber, but I wanted to choose a local company for the job. The fact that this company only had one star made me kind of nervous, but I thought — well, just because they don’t have reviews does not mean they are bad, I’ll give them a shot.
I called — and there was a message saying «This call may be recorded for quality assurance» which I actually found somewhat reassuring. Someone then asked how they could help, I asked about getting an estimate, and the call ended. I thought maybe we were disconnected…
I called back, three times… I still got the «this call may be recorded for quality assurance» bit. It would ring once or twice, and then two quick clicks. So… the call wasn’t getting disconnected, I was just getting hung up on.
No wonder there is only one reveiw! No one can schedule service!
I looked at the website and could not find a license number. I searched the name — and there are tons of J S Plumbing throughout CA. Some licenses are active, some not — which one is this? I don’t know.
Well, now there are two. Services or not. Good luck!
