Minama (Thailand) Co., Ltd review: Cheated us by sending wrong products 1

This is Asir from wellcare trading and contracting Est, located in Eastern Province of kingdom Of Saudi Arabia.
We are industrial suppliers for Petrochemical Industries. Recently we purchased some metal plates from your Thailand company(MINAMA) worth $ 38, 400.00.They have even taken 3rd party test money also from us, But after receiving the material we see that they have cheated us by sending us Wrong Grade material, low quality and wrong specifications with duplicate punching of grades on that(material worth 3, 000 dollar have been received for 38, 400 dollar). After receiving the plate we have tried calling Mr. Rantipak or Yanisa from Minama Thailand Company, but nobody is responding to our calls and many times we have sent the email to them also, but no reply from their side. so anybody dealing with minama thailand company be cautious.
