TELEPHONE CUSTOMER SERVICE-ROBO CALLS,

Common problem and until the government and ALL the Telco's can agree on a tactic to combat this it will continue.  The piecemeal approach of giving the consumer "more tools" is not the answer.  There are bills in the congress, Senate to be specific to address this, but as far as I can determine there's been no agreement reached.  No one company can do this on their own because of the many data bases used.

There's many topics on this subject, both on this forum and by using your favorite search engine.  The person you contacted can do zero about it.  

Here's the latest on the Senate bill from about a week ago.  It now goes to the House.  

This is just my opinion, which I'm known to have a few.  Until they get rid of the money in this and the "everyone but me" lobby they will never seriously address this issue.  Overseas companies where most of these originate could care less about US laws or the fines they impose. Shaken/stir is a start, but it doesn't go far enough and at the present time only T-Mobile is making much of an effort at it.  Like stated above none of this will work until ALL Telco's are onboard and it's probably going to take federal regulation to make that happen. 

I agree with you! What I don't like is that we pay ATT for our phone service. I know they could easily set up a program that would use caller I.D. to block numbers that say "unavailable" or "spam" or "telemarketer" etc. Greed is the only reason they won't.

Unavailable, unknown, no data sent, those are basically what they say, if there's no data sent as in those three examples than there's nothing to block. Also there are times glitches happen when the data does go through, yet it's a legitimate call.  The "possible spam" is fairly new and is mostly used on VoIP and wireless services, but just because it says spam or possible spam doesn't mean it is.  Anyway it's just not as simple as most people think and believe it or not there are certain calls the FCC doesn't allow the phone companies to block at this time, one is 800 numbers so if everything else were fixed by all the phone companies working together yet that rule wasn't changed by the FCC than overnight the spammer and those spoofing would simply change to 800 numbers.  The greed part I agree with as they are making money on these connected calls.  Just use your favorite search engine and see who all is exempt from the current do not call rules.  Prepare to be ticked off.  At any rate this subject has been pretty well beat to death in numerous topics and articles.    

USA today article The latest statement.  Shouldn't surprise anyone the phone companies want $$$ to do this.
