Bad service and even worst attitude

Never experienced bad service quite like this.The manager had this attitude like the customer is reliant on their business and talked to me in a manner like if I was one of her friends or an illiterate fool who was just there to annoy her.Besides the wrong information given about the product I bought she just had that don't care attitude who also refused to give her name and surname when I said I'm going to report her and the company to the CPA. I've asked some of the staff for her details they also refused to give it, probably afraid of being victimised.This all happened because I've bought a 20L paint and was told by the sales person to buy orange tint and the end result should be peach which I wanted.Did the mixing and it turned out pink so I've called the store and asked for the paint the dept. Then I had to endure the staff debating who's going to take call in the background only to be told once again to bring it in. Took it back to the store and the manager told me that I had to pay an additional R240 or they can send out one of the contractors in the morning.This all being said and done with an attitude.I'm the one that's supposed to be mad and frustrated what's her excuse?
