You requested multiple commissions from a person without checking if they would deliver even one? You'll get no sympathy from me. While you're going about throwing money at random people on the internet, want to toss some my way? I promise you'll get exactly what you pay for.
Several commissions? You mean you asked for several instead of waiting for one and to see what would happen with that one? I can understand one commission. But when you took the second one without even receiving the first one, you only have yourself to blame afterwards.
