Called my cell phone on a Sunday.  Noticed the call today and called back and got a recording/bot that the CALL CENTER's mailbox was all full.  Blocked this call and reported to the robootguy.

2 second message left..sounded like a robot call hangup. blocked.

6-15-17 09:51 PDT CID "DOWNEY CA" New number calling. Hung up after 4 rings. It now becomes blocked number 350. Internet search shows spam, spam, spam. U-all take care.

It's either solar construction or a fake cruise scam

6/19/17 14:33 PDT  Another addition to the Downey   CA  list of numbers proliferating locally.  What a pain these creeps are!  Didn't answer and no message was left.  Number now blocked.
