PATHETIC CUSTOMER SERVICE. ARROGANT OWNER!!!

Absolute horrible customer service. Took my niece there to get some stuff for her birthday, she wanted some nail polish and we saw a sign that says buy one get one free, so we took 2 and a few other things. upon paying we were told that we have to buy 2 nail polishes then only will we get the 3rd free, we then said to the owner that the board clearly states buy one get one free, but he was adamant that we were wrong, we were going to pay just to get the two nail polishes, but the lady working in that isle brought the board and told the owner he told them to put it up. He then proceeded to take the board and tear it up and he started being rude, gave all the money back and told us to take our money and leave all his stuff in absolute abrupt rude manner. Would advise people not to go there as he also changes prices at the till and when trying to explain he gets rude.
