supplier help/ RT Specialties

I ordered parts from RT specialties too and after 2 weeks I'm still waiting for the parts. I called and he finally picked up the phone after 3 days. He claimed he shipped the parts on a Monday but BS'd me cause I later found out from the tracking number he had not shipped them till 5 days later. I never got a email with an invoice either. In the meantime I'm still waiting for my parts. Never again with RT.
