Same lame Scumbags.   Different Spoofed Number "515 512-1035" CID "Unavailable" Spewing Telephonic Diarrhea in hopes of fraud.  Didn't work - the Call Blockers sent it straight to the crap zone - Like I'd be curious or STUPID enough to answer the call after getting hundreds of these jerk's calls... what a bunch of mental midgets!!! They all get promptly sent to the TelecoToilet for flushing to the sewer the calling human sewage crawled out of...
Some other scam call reporting sites already show this number-reports are that it's one of the typical "Threating Call" type scam.

Same turds called in the past few weeks and months using:
515 351-3131 CID “I Wireless”
571 319-5624 CID “Arlington, VA”
515 212-3547 CID "Unavailable”
515 619-5849 CID "Unavailable"
To All The Callers - ESAD JOs  Time For a Nelson Muntz :  "Ha ha !!!"

Any call with CID "Unavailable", “Consmer DBT RLF",“Customer SVCS", "Consumer SVCS", "Wireless Caller" Etc. is 99.9% likely to be a scumbag - DO NOT Pick-UP and engage the turds - it only confirms the number has possible suckers on the end and it gets circulated as part of the universal scammers phone list...

Unknown number so I did not answer, they left no msg.  From other comments regarding this number I believe they are scammers.

Called @5:30pm. Let it ring through to auto generic message.   Left no message
