Sportscene Jabulani Mall

I went to Sportcene Jabulani Mall and bought a few items and I was told by a cashier that a jean I bought comes with 2× free sneaker labs and he went and fetched them. When I got home a just got a feeling to check the receipt, which I did only to find out I was charged R200 for those things I don't even use. I believe this is what they do to many customers and some don't even check their receipts. Lehlohonolo @ Jabulani Mall must pay for this because I don't want these things. I was told that I'm not allowed to return them.
