I keep getting these calls on my cell phone, anyone know how to stop this. My cell phone company says I cannot block this number.

Company said it was Global Travel. Won a "FREE" trip aboard the Bahama Celebration Cruise Ship, departing from Palm Beach in the Grand Bahamas. Take the trip anytime within 18 months, meals included, all the fun blah blah blah....now we need your credit card number...they give you the name of the Senior Travel Coordinator  and their ID Verification Number. Working very hard to get your credit card number. If it sounds too good to be true.....IT IS! Beware!

My complaint is the same as the telephone customers.

This number keeps calling my cell phone 2 to 3 times a day.  If I answer they hang up.

rec'd 3 calls from this number but they hung up when i answered.  They are calling my work number.
