Thank you for posting this information.  I had my suspicions that it was Spark Marketing calling us, so after reading your post yesterday, I sent the "US Partner" listed on their website an email (jon.adler@sparkcallcenter.com) about the repetitive calls to our office for someone who isn't here.  He emailed me back today and apologized.  He also said we will not be called again.

I hope the other people they are wrongly contacting can get the calls to stop as well.

So far, the calls have stopped.

Well, the calls started back up a couple weeks ago, first from blocked numbers and today from 231.537.1439.  So much for Jon's promise that they wouldn't call again.  His number is 949.754.3044 if anyone wants to try to get them to stop calling, but I fear it's futile.

Just received an "abandoned" call from these idiots.  They do use different phone numbers but the best way to combat them is to report them to the FCC.  Fill out a Form 1088 (online) it only takes a few minutes.  If the FCC gets enough complaints they will do something.  I suggest you fill out this form for every scam call you get.

Continues to call every day even after I've left messages demanding they remove my cell phone number and that I've reported them to the FCC.  Is there anything else I can do to stop the calls short of tracking down the physical location of their automated dialer and ...???
