No one else reading this page can ''help stopping'' anything on your behalf. Your caller is not going to dutifully study random forum complaints and cannot magically determine which numbers should not be called based on anonymous comments.
If it's still a charity caller as reported prior, DNC registration isn't helping. The DNC registry is for telemarketers, meaning sales. The following URL links to the FTC FAQ page which the DNC site *twice* coaxed you to read before you registered your numbers. See items 28 through 32 in particular.

However, much of the charity phone bank work is farmed out to so-called "commercial fundraisers" such as Associated Community Services, Dial America, Harris, InfoCision, MDS, and TeleFund. Commercial fundraisers don't quite get the same blanket exemption. Here is the holy writ of FTC: ''... if a third-party telemarketer is calling on behalf of a charity, a consumer may ask not to receive any more calls from, or on behalf of, that specific charity. If a third-party telemarketer calls again on behalf of that charity, the telemarketer may be subject to a fine of up to $16,000.''
Didn't leave a message. Gets through "Privacy Manager," which blocks most annoyance calls. Has called repeatedly over several days. Probably collections.
this number was on our phone system with a listing of "Public Safety" which we did not answer. they called without leaving a message on 6/26, twice on 6/27, 6/28
This same phone number and name has shown on my caller id twice now and i dont know who they are or what they want. I was not home when they called and I dont have an answering machine.
