On June 28,2016, I was contacted by Vibe Global Tech LLC and spoke to a Mr. Nicklos Johnson. I purchased a $4,500 Bitcoin Antminer. He verbally promised 2-5 block chains per year, I haven't gotten one in over a year, nor have I recouped the purchase price. I've made $1,294.00 and have tried to contact them as to how to exchange the bitcoins, but no one answers the phone or will return my calls. I wrote to the Better Business Bureau, 1010 E. Missouri Ave., Phoenix, AZ 85014 (Maricopa County). They wrote back and basically said there weren't enough complaints to warrant action.
