571-210-4826 Robocalls my cell phone. If I answer, the recording says "Home Services".
I tried calling that number from a land line and a message says that it is a "Weight Loss Center".

These dweebs have changed their number over two dozen times these past three hears. I actually tea led them the past three years. The same tired [***] hard up woman says the same tired thing about being a past customer. Of course this is pure pile of hoarseshiitt but they seem to be searching numbers with a heartbeat. I never do more than hang up when I hear miss [***] start the recorded schpiel. But who are the real [***] behind this effort? I only know what they are. F..em.

The way to stop this carpet cleaning stuff is to make appointments with them and, when they show up, tell them to get lost.
If a couple of hundred thousand people do that, this marketing ploy will stop.
If they say they need a credit card, tell them they said you were a customer so that should suffice.
It's about the pocketbook and a few hundred dry runs per company will lead them to stop using these referral services.

No, that's just an attempt to cover their own behinds because they know that the Do Not Call registry allows them to call anyone who has been a customer or has contacted them within the past 18 (I think) months.  Apparently they think that no one will report them if they make that claim.

Called back, said it was a weight loss company
