Very poor shoddy service

I bought SETA accredited material from this company in December of 2017 and paid up front as requested. When I received the material I saw that it was not SETA compliant. I have requested at least five times for the materials due to be to be sent through. Nothing has been forthcoming. Today I have two of the people in the company hang up on me or refuse to take my call. If this is the type of service they offer I warn other customers not to use them.
