If you've ever called warrior custom golf, your number is probably added to an auto dialer for selling golf equipment at the cost of shipping only. Still an annoyance.

They always call and never leave a message. What I did was download a free program on my phone that blocks numbers or area codes. The minute your phone starts to ring it throws them to your voice mail. If you don't want that It will just pick up and hang up on them auto where they cant leave a message.
