Lots of slant six parts

I talked to Charlie about offy intake #2 on thursday, and on friday night he agreed and told me to paypal him. I sent it within a few hours and bought some other parts to go with it.

Today he said someone else PM'd him with another offer before I sent the money and he would refund me... In my humble opinion that is not right, as we had an earlier agreement, and there was no mention of this other deal before I paid. Just thought the other party should know this. Normally I'm understanding but I'm not sure what I'm supposed to do with the other parts now.
