Got A call and didn't answer because I didn't recognize the number. Called back with *67 and got a greeting only asking me to press "9" for their do not call list...that would be a way to automatically verify that my # was valid for more telemarketing calls (I'd I hadn't hidden it in the 1st place). Sounds fishy to me.
Called 2 hours ago. Didn't leave a message. Blocked. Got another call from the same area code a couple hours earlier saying I can enjoy a trip to Orlando. Hung up and blocked that one too. I assume it is the same telemarketer.
