Cross trainer jabulani mall is a ****, do not buy there!

I would like to warn anyone who wants to support this reatail especially from Jabulani mall, you will regret setting foot in that shop. I did a laybuy at the store of a vans, well the cashier used a standard bank speed point and it did not go throough, I do not know why, then she tried again using the Fnb speed point then it approved. The shoe costs R550 so I was told to pay 250 which I did not have a problem with, I got my slip and left the shop. When I git home another R250 was deducted, I then went to the store to take out the layby and pay the remaining R50... To my surprise, I was told that I owe R300, not R50. It has been two weeks and I am not getting any help or refund. I regret buying my sneakers from this shop. They are all s**** heads.
