bad service.they dont give change.bad attitude

I bought an air max sneaker at plaza cross trainer for my 2yr old son and it didn't fit him and I went for exchange and they didn't have a size I was looking for they didn't even want to order for me and yet they can't refund me. I then took some clothes which were then too small bcoz it was tagged wrongly on the units when I reached home it didn't fit my son due to their wrongly tagged size. I then went to exchanged it against at RIVERSIDE MALL NELSPRUIT a day after I bought the clothes and I found a manager. She was the one who was assisting me she told me I won't get my change back since I took something that is less by R130 and they won't give me my change back bcoz their policy says they don't give cash back therefore I must take something for the same amount but I never wanted anything else. She said my change will b for cross trainer. And when I told her about ombuds and CPA she said they don't apply with any Rules of CPA or OMBUDS coz its a stand alone company for one person. I will never ever ever ever shop at cross trainer and won't recommend it to anyone I know... A shop with no cash refund noooo a shop that doesn't give change if u exchange and take something less noooo
