JEGS A/C Safety Switch [Trinary, In-Line Beadlock Fitting]

I bought one trinary switch kit and was charged for two. I called to have one of the kits taken off the order the next day but that was not possible. Supposed to have a shipment form to mail the one kit back for a refund but that never came in. Crimped my lines to add the trinary switch and the switch does not thread into the fitting provided. I paid over $100 to have this garbage added to my ac lines and it doesn't even work. I will never order from jegs again. Very unsatisfied customer!
