Do not shop here - they owe me more than R6k

I bought a kitchen sink at CTM on Friday. I wanted one with a pre-cut faucet hole. The sales person showed me one of the floor models with a pre-cut hole and so I bought it. Upon collection I checked and saw no pre-cut hole. I asked the sales person why she **** and she said there were markings underneath to guide the hole cutting - I checked and one of the dispatch guys checked as well and there were none. So she **** to me again. I asked for the whole purchase to be refunded. Their useless card machine could not refund back to my card and the refund transaction was declined twice. I asked to be refunded in cash and they refused - said they did not have that much cash in the store, even though there were many customers paying cash while I was put through this ordeal. The manager went into hiding and so they got the deputy manager. Then they wanted to email me a form to fill out in my own time and for them to refund me in their own time via EFT. This after costing me bank fees for the purchase transaction, lying to me about the product, refusing to refund me in cash (which is in violation of the consumer protection act), and wasting more than an hour of my time processing the refund. I had to ask them to email me proof of this utter disgraceful refund failure because they would not provide me with any proof that they owe me more than R6k. I am still waiting on my refund and I am taking the matter further. I emailed CTM customer care and they have still not rep****.
