Horrible service by Markham staff

On Christmas eve 24/Dec I came to clearwater mall store to purchase a JD sneaker which was not in the store and Paul convinced me to buy it through him online after he **** to me that the shoe is no where in Gauteng but only at their warehouse and the following day I found the shoe at Jozi Markham.... Pual order an extra pair of shoes without informing me and now am at the store am telling them I need my whole money reversed and they refuse to reverse it all
