Exchange of new shoes

I want to express my disappointment at the manner in which my request was handled. I bought 2 pairs of buccaneer shoes Clearwater mall on the 10/01/16 for my daughters for which they fitted on on the 12/01/16.They wore them on the 13/01/16however after going to class they started complaining about the shoes.Alleging that they were hurting.I immediately ask them to take them off & approached different stores for exchange of sizes for which I couldn't find except at Cresta.I then requested to be exchanged only to be told that they've been warn.I didn't dispute it but agreed and showed them the slip,they still had price tags and they were wearing those shoes today for less than an hour.Those shoes had dust and of cause if you walk with a rubber of a buccaneer it peels off. I appealed to both managers and they didn't want to understand.Worse Sindi refused to call someone senior claiming that she was the only senior person until I met Teballo.I found it to be unreasonable without considering the facts in making their decision.If they were really damaged and couldn't be sold, shouldn't the quality gets questioned because they were warn less than an hour?I'm really sad about the incide
