Got a call from this number and I did not pick it up because I do not know anyone from Crestline. I immediately called back from a blocked number to see who was calling me, an automated reply came on and said "Thanks for calling, this survey you were called for has now finished. If you like to be removed from our list for future calls, please press 9." Be wary, folks, I can sure smell something fishy!
Remember, do not answer if the number is unrecognized. If they are really legit, they will leave you a message. Also, answering your phone validates that it's a working number. Do not let these scammers take your hard earned money!
