Sunninghill Cash Converters - stay away and do not support

The owner of Cash Converters in Sunninghill without any doubt has the worst customer service ethics I have ever experienced. I have for a week been dealing with one of the assistants David to ask the owner if he could drop the price of one of the many electric guitars they have on display. I was interested in an amplifier they have and decided to also try and buy an electric guitar. Being a pensioner I felt they could have assisted me with even R100 discount. Today the owner who has the worst manners and ethics I have ever seen, basically brushed me off saying he is way to busy for me a customer and that just a no not interested and then walked out the shop. He lost a R1900 potential sale by just accommodating my request for a R100 discount. I WILL NEVER shop there again and will definitely inform everyone to stay away and NEVER support them. Utterly disgusting service - I really hope that Cash Converters Head Office look into this very seriously as the Sunninghill shop is utterly appalling. Who does the owner think he is to treat people like this?????
