Paid 1600 for Sliding door an transporting 600 but no Sliding door in tea wd sent pillar to corner.

I ought a Sliding at Built it Vosloorus September 2023. When it was not sealed but wrapped with sellotape. On opening found it's not completei. I went to tell them the Salesmen said l must bring mind you m using transport to bring it to them. Later after some days l called them as they were quiet. l was told to wait untill they used one of Salesmen to call me and say he is a supplier. I personally drive to shop and there was no Supplier instead Manger chased me out and threaten to call police. Untill now my money has just paid for nothing 1600 plus transporting 600.l just want what paid for siding for.
