They call all day long and don't leave a message. When you call them back it forwards you to an voice mail box. I've left messages and asked them to stop calling. They won't stop calling.

didn't leave message, called twice

Please, stop calling!

Said I had won a $100 gift card from Walmart. All I had to do with pay $5.95 shipping and handling with a credit card. When said I wanted to look up their site on the internet, the person I was speaking to hung up.

This number keeps on calling and asking for a Luis Martin.

calls come through several times daily to my mobile number.

Just pick up the call and tell them to "please hold" and put the phone on mute and leave it there until they disconnect. Waste their time. Their time is money and if you tie them up on a call with no results, it counts against the telemarketer's individual rating. Hopefully this can lead to them not trying it anymore. Blocking numbers won't work, because they are using a caller-ID spoofer that can send any data they want. Don't get angry. Just get even!
