Poor service

Received poor service from fair price in vanderbiijlpark. Wanted to buy an ottoman that was on promotion, a 95l freezer and a bigger ottoman. The sales guy said we can't take the Ottoman on display because it is the last one ... I had no problem to buy the one on display but he said I must take something else that they have more stock of. Why do you want to advertise stock if you can't sell it. No use of having something on display if the public cant buy it. Will never visit then again.
