I got a call from this number saying that i won a trip to Florida and the Bahamas.I told the caller i was not interested.This is the 3rd or 4th time i have recieved a call from these people and i have them i wasnt interested in what they were offering.I feel like im being harrassed and i dont want anything to do with them.When i told them today,that i wasnt interested,they chose not to listen to me and continued to agree to they're offer.Is there any way to immediately stop these annoying and harrassing phone calls?
