Same here, no message. I called the number back (from another phone) and it said "thank you for calling. The survey you were called for has ended. If you would like to be removed from future surveys, please press....." That's where I hung up lol. Will block the number for any future calls.
1-210-245-7481 is a garbage number!!! When you answer no one talks. When you call back you find out it's some kind of survey....it's a BS call. Add this to your list of BS calls!!
