Left on another site by someone else getting these calls:
The reason these same automated calls appear to come from all over the country is because they are ALL personal identity phishing SCAMS! There is NO service or telemarketing company to bother wasting time with reports to the Do Not Call Registry. After some months of this nonsense, I only discovered the truth behind it from a rep at Chase Bank who said they knew all about this racket because of the apparent similarity to one of their divisional names. The ONLY answer is to IGNORE such calls, however much they proliferate. And maybe refer any caller ID info (number, date, time, city and/or state of origin) to the FBI as I did for further investigation and, hopefully, correlation of numbers and locations to sting these criminals. At least one advantage I found of keeping the multiplying numbers in my iPhone from continuing to distract and irritate was simply to assign them all to a single contact I titled "Card Member Services" scam AND then assigned a SILENT ringtone I'd devised so I would NEVER hear any prior numbers calling again. In the months since, I've cut the times I actually hear any new number ring from several a day to just one a week, at most. And then pass it along to the FBI . . .
Every time I get a call from an unrecognized number, I wait for them to leave a voice mail. If no voice mail is left, I Google the number to find out if I've got a scammer. Once I've verified that other people are having trouble with this number, I assign a name (like "Scammer1) to the number and save to my phone book. Once I have a contact in my phone book, I can then program my phone to send that call directly to voice mail. I only hear from these jokers once and then *poof* they're history! Calls have dropped off from several a day, to once a day, to once a week, to once a month.
