You are NOT out of line, there are many firms doing this. Witt Machine from Childress TX are expert at it. I have 2 emails committing to refunding me after 3 months' delay, still nothing 2 months later. Cant get thru on the phone. Check their online reviews....horrendous. I got taken.......Cool...
Ken Wittekiend of Witt Machine is a crook. He takes your money in 1 millisecond, goes silent, replies by email that his non delivery after months of asking is your fault, promises a refund, and goes silent again. Not bad for a man who professes to produce silencers. Please do NOT accept my words...
