Didn't answer then called them back recording said if you would like to be removed from call list press 9. Still don't know who it was. Obviously it was a robo call checking out #s.
Called, left no message on my answering machine. Caller id on my phone said "Warwick, RI". I returned the call less than a minute later (with my own caller id hidden) and a recording answered that "the survey I was called for is now closed." So I blocked the number, as it is obviously a scam. The same recorded male voice answers at 401-396-2331, 401-608-3009, 401-396-2343 and other Rhode Island numbers as well, all of which I have blocked.
