The worst, extremely rude and irresponsible person

On the 12 of March I placed an order for caesor stone counter top with Granite World Company. A man by the name of Chris took my order and on the same day I made an EFT of R1250 My builders only finished the plumbing work on 2nd April 2015. I called Chris to book me for my stone to be delivered and installed after Easter. Every other day his rude excuse is how he runs a big company and he doesn't only focus on me. You call the office, its him who answers the phone and hungs up. He then sends a whatsapp message claiming to be in a meeting and sending me pictures of his factory telling me he is a busy man with plenty of customers. The last straw was when he said its raining and the stone cannot be cut in the rain. I found this strange. I called other companies who confirmed this to be a lie. On 13th of April i cancelled the order and since then he doesnt want to refund my money but instead sending me ugly whatsapp messages. One company confirmed that they have two clients who left Granite World because of the same ugly treatment. I need this idiot to be brought to book. He needs us customers but instead he treats clients like beggers. He should be FIRED! No one can identify the owner
