Terrance from slab world takes customers money and refused to deliver material

My constructor bought the slab from Slab world in November 2022. Since then a guy who happens to be the owner Terrance, keeps on promising that he will deliver and even today 19th january 2023 i am still waiting. I had to engage with him every day he promised to deliver the next day since december . He took the money and now he doesn't to deliver or to payback the money. To me this guy is fraud.
