United Processing Legal Dept. review: united processing services - harassing

They have been harassing me. Told them I'm not taking down any number if they have something to deliver to me then do it. I told them it's a scam and to stop calling me. He hung up on me and then has nerve to call me back and prank me. He then called back again and played like we never spoke.. I said "chuck I suggest you knock it off cuz I'm not playing!"..he hung up again. The phone number he called from says Las Vegas NV [protected]
