Bad customer service

I had a bad experience with incredible connections where I was charged 15% when returning the new laptop. I went into the store and ask for a fast laptop, the sales person is so ***********, didn't even asked my budget and I told her that I'm running a business and she recommended the basic which I only find out when I return the laptop because it was very slow even to start. They should train their sales people to ask the right questions. I lost my R900. They recommended that I buy another one with a faster processing system but I was so ****ed I didn't even want to spend my money with them anymore. Bad customer service.
