I have been getting calls from 1-877-252-2916 on a regular basis but they never leave a message.  This may very well be some sort of scam in progress.

same ... no message left. Next time I'll answer to see what more I can get.

I find this tho,
"Blue Lake Casino, 777 Casino Way, Blue Lake, CA
(877)252-2916 (Local)
(877)252-2916 (Toll Free)"

however, that seems to be a bit misrepresented. They are actually at:
1(877)BLC-2WIN or 1(877)252-2946 the "I"' seems to have been mistaken for a "1" when the number was setup on the site outside of bluelakecasino dot com

Called my cell phone 4 times in the past 24 hours.  No messages, picked up and they asked for Mr. or Mrs. (my last name).  Judging from other peoples notes this is a scam.  Don't give out any personal information.

Have gotten several calls from this number in the last couple of weeks. they never leave a message and I've never tried to call back.

Even if it isnt a scam... Charter sends me a metric ton of self-advertising every month so I really dont want to hear it over the phone.

This number has been calling every day around 12:30 -> 2:30pm.

I will not answer, I am sure it is a scam.

Calling my cell phone,sometimes twice in 24 hour period

This person/number has been calling me.  I have been ignoring the calls but they call every day.  So i contacted Charter myself last night and they said they dont recognize the number that there was nothing listed on my account.  BY that I mean, they saw no reason for them to be calling me and they said they would document the situation.  

So, When the the person called me tonight I was like "may i talk to your supervisor?"  And they said they were unavailable.  Then i asked her if she could look up something on my account for me....she hesitated and said "Im from a different department...."  I finally just said "Im not an idiot, you're not from Charter.  Stop trying to scam people and get a life and stop calling me..."

She hung up

Keep getting calls from 877-252-2916 with no message left... I never answer but just looked the number up and found this:
"Blue Lake Casino, 777 Casino Way, Blue Lake, CA
(877)252-2916 (Local)
(877)252-2916 (Toll Free)"

So...if they are claiming to be Charter Communications, it appears that they definitely are not, and might be coming from a CA casino! Don't give any personal info!!

As of today, about 50 calls from 877-252-2916 over the past month with no message left.

I have been getting calls from the number 877-252-2916, but would leave no message.  I don't answer calls from numbers I do not recognize.  I googled the number and found this site.  I tried calling the number back and it also claimed to be Charter Communications.  Not sure why they would be calling me.  Well if it's anything important then they can leave a message, until then I'm not answering it.

Claimed to be Charter Communications but the person I spoke with did not seem very well versed in anything related to charter. Sounded nervous, unsure and I cut it off right after he tried to "Verify information". Seems shady.
