I have received multiple calls from 703-988-5233. The caller has a foreign accent, yet claims to be "Bob Smith" with "U.S. Auto Com Center." He immediately cuts off any attempt to address him by going into his sales pitch about supposedly providing me with 3 free quotes for automobile insurance but wants to verify my mailing address and vehicle. I ask him for his mailing address and he ignores my request and continues to tell me about the free quotes he wants to send me in the mail. I again ask for his mailing address because I need to send him a letter in the mail. Then he tries to give me what is probably a fake EMAIL address.  I insist that I don't need an email address but need a physical mailing address because I need to send him a letter in the mail. Mid-sentence of my request, he hangs up on me. This has happened several times already.  

I called the number back immediately, only for it to go to an automated voicemail with the following message: "You've reached a Pinger number. We'll let the person know you called. To get your own No-Monthly Charge Unlimited Texting and Calling number, go to Pinger.com. All I can do is hang up now; why don't you go first so I don't have to hang up on you."

I went to www.pinger.com to see what options there were to file a complaint on the number and they do have a reporting option. Below is the information on their page regarding harrassing calls or texts:

So I filed a quick complaint about the harrassing calls. Hopefully they'll resolve this. In my report I also included the following.
I should not have to continue to be bothered by these calls and I shouldn't have to just ignore the call and "not answer it." This line is my personal business line and I cannot afford such time wasted with this nonsense.  Please consider this my formal request for this number and any other numbers said company also has purchased from your organization to cease contacting me. This is a violation of my rights and is against the law. It is considered harrassment to keep calling me, not to mention rather rude to hang up on me when they called me to begin with.

They call themselves "Auto Care." Told them I was happy with my insurance, they said they weren't trying to sell me insurance, but would I like to hear some quotes? As I was hanging up they asked me something about my credit card. Have to pay extra to block calls on my phone but this number went straight into my "Don't Answer" folder.

"Auto care" calls me about once a week trying to give me insurance quotes. I have fun messing with them before asking them again to take me off their call list. Last time, I made the guy really mad, and he was like F this, F that, F you, F your mom and sister, I'm gonna sue you for wasting my time, yada yada yada. It's their choice to call me, I make sure to get a kick out of it so my time is not wasted.

applied for auto insurance quotes online 4 years ago! they've been calling me ever since and will not stop upon request, although they say they will delete my number from their list

Like clockwork, every time I apply for a job online....I get calls from this phone number 703-988-5233.  I believe the online job board administrators are selling job applicants personal information to marketers,  and the government does nothing about it,  That IS NOT right!

The caller is calling about saving money on auto insurance....They call all the time and I've asked them to stop calling me but they won't stop.  I don't know what to do.

I have been getting calls from this number every single day, like clockwork. I normally do not answer unknown numbers, so I have been ignoring them. Today I was at work when they called and I was so irritated with them that I actually answered. The guy asked for me by name, but I told him it was a wrong number and to stop calling. After I hung up, I instantly regretted not asking who the heck they are that keeps calling. I attempted to call back and it doesn't even ring. A recording  comes on and tells you that you've reached a "Pinger" (I think that's what it said) number, and they will tell the person that I called.
