When someone answered, I asked them the name of their "warranty" company and he huing up. Tried to call back and got voice mail.

Recorded message I do not bother to listen to.

Such prerecorded calls are commonly used by shady companies selling car warranties and are totally illegal. The Telephone Consumer Protection Act (TCPA) forbids unauthorized prerecorded telemarketing calls.

The FCC enforces the TCPA and you can easily report these illegal calls online to them here: https://esupport.fcc.gov/form1088/consumer.do

The caller is a prerecorded car warranty services, specialist or some such thing, supposedly. They are not just a nuisance, but have been harrassing me over a period of months. They very well may be a scam. They call from multiple numbers with various area codes, the most common being 352 -357-4151. The caller ID says various phrases (this time is was gift center) or people's names I do not recognize (once was Richard Simmonds). Very rarely says warranty, or may say nothing. There is never a real person. Often, messages are left on my machine. They call from these various numbers approximately three times every day during the week and a few times less during the weekend. So far, I estimate I've received between 1000 to 3000 total calls from them. On another page of this site, with one of the other numbers they used, someone reported that pressing the number to be removed from the list does not take you off of it, but directs instructions to the "Do Not Call List". I do not know if pressing either number will cause charges, or allow them access to your line or do any other unwanted action. I have been seething multiple times at their calls, and cannot believe the negative energy the dredge up in me. Maybe this gives them satisfaction, if they read this.

This number has called us numerous times.  
Based on what others' have said this other number 978-485-0163 "The Underground" is offering a car warrenty as well..
What should we do?  Call the FBI?

Called at 9pm.  Asked for my make and model, I said no and that I wanted to be taken off their list.  They hung up before I could finish what I was saying.  They've been calling for months.

These people have begun calling me and they hang up when I ask about the services that they are offering. It is quite annoying.

This is just one of several numbers that have been calling both my home and work about an expired car warranty.  This has been going on for several months and there seems to be no way to stop it.  If I hang on and reach an operator, they either hang up on me or in one case gave me a "do not call list" number that was in actuality a number for a phone sex solicitation!

These people have been calling my home for three months about extending some care waranty.  They claim to be the "Waranty Services Group" and the Caller ID says the number is from Parma, OH.  440-499-0407
