Horrible customer service. bought a jammer from them on May 2 and received a non working unit. they promised to send a replacement but nothing happened for 40 days until i disputed the charge. its only then they called me and asked to cancel the dispute. i canceled it but they still didint ship the replacement, claiming they didn't receive money from American Express yet. they suggested i send them another 450 via Zelle to expedite the shipping, i did and they still didnt ship anything. it took another month for them to ship the replacement, but now im out $900 and only have one working unit. When i asked to get a refund they said the unit i shipped back to them has a different wiring, which is absurd, where would i get a different wiring to a unique proprietary piece of electronics? i disputed the charge again and they responded by saying i just returned a USED unit to them so they will charge me $120 or something like that and refund the rest. Still havent received a penny. STAY AWAY FROM THESE PEOPLE read more
