bad deal
So why not retract this and see if the guy sends you the parts/money in a reasonable time. If he gives you a verifiable tracking number in say 2 weeks then you get what you want even if it is late.
If he does not make good all you have to do is get back on here and start another subject on him.
If he makes good, you should also come back on here and say all is good as far as parts or money.
If indeed you won't call him to work it out, that doesn't look good on your part either unless of course he does not answer.
