Samsung S5 smart Phone

Hi,<br> I wanted to buy samsung S5 smart phone at Hifi corporation in Beacon Bay East London on friday 4th of December 2015. It was marked down from +-R10100.00 to +- R7450.00. The manager said she will reserve the phone for me its the last one in stock and i will pay on Sunday 6th when coming to collect the phone. On sunday i popped in by the store to pay for the phone I was told by lady acting manager on the day name Angela that i cannot buy the phone. She took away the dummy phone on the shelf so that i cannot take a picture of their advert. She refused to sell me the phone saying the phone is out of stock. I told her I was the last friday and the manager reserved one for me. She still refused. The sales man by the name of Musa was there to confirm my claim to her but she would not agree to sell me the phone. She told me im inconviencing other customer and she ask me to leave the store. Im told her to call police to remove me because what she was doing is ********. the were still showing the phone to the customers on the shelf but not having it in stock. I want this phone on this price of R7450.00 please help me.
