call this morning at 9:30am but they did not leave a message

I did not answer and they left no message. Seems like I recall seeing a call with the caller ID once before, some months ago. So, I Googled L7 SVC CALL and 800Notes had calls reported from that caller ID for:
3602157344
4022351368
360-215-7336

Caller ID showed "L7SCVC CALL"  Left no message

Called 4 times in one day, no message

Report this call and any others to Tom Wheeler, the Chairman of the FCC.  His email is tom.wheeler@fcc.gov.  They will send you a form to complete so they can take action.  Below is the email they sent to me:

You are receiving this email in response to your inquiry to the FCC.

Thank you for your e-mail to Chairman Tom Wheeler regarding a telephone scam.
While there are many legitimate companies that use the telephone for marketing, consumers and business lose millions of dollars to telemarketing fraud each year. It's sometimes hard to tell the difference between reputable telemarketers and criminals who use the phone to rob people. You can protect yourself by learning how to recognize the danger signs of fraud. If you are a victim or attempted victim of telemarketing fraud, it's important to report the scam quickly so that law enforcement agencies can shut the fraudulent operation down.
Some of the various telemarketing scams are:
-Government Grants - Nigerian Money
-Loan Applications -Business Opportunities
-Fake Check Scams -Credit Card Loss Protection
Remember: The government doesn't telephone people offering money. Most credit card companies offer loss protection for free. Offers of business opportunities that are too good to be true usually are. Fake Check Scam is similar to Nigerian scam- callers are offering to pay for something you are selling via a third party because they are in another country or they are in another country and need an advance, etc.
You can file complaints about various scams with the FTC or your state Attorney General or consumer protection agency. For information on how to file complaints with the FTC, visit the FTC Web site at www.ftc.gov or call toll free at 1-877-FTC-HELP (1-877-382-4357); TTY: 1-866-653-4261.
Contact information for your state Attorney General's office or consumer protection agency usually can be found in the blue pages of your telephone directory.
You may want to put a fraud alert on your credit report if you feel they are trying to steal your identity.
Victims of identity theft may contact the fraud departments of the three major credit bureaus, report the theft and ask that a "fraud alert" be placed on their file and that no new credit be granted without their approval:
Equifax: 1.800.525.6285
Experian: 1.888.397.3742
Trans Union: 1.800.680.7289
Contact you're bank to make them aware there is a scam. Also, contact your local law enforcement regarding the threats and notify your local newspaper so they can get the word out to other consumers that there is a scam in your area.
I hope this information has been helpful.
Thank you
