Different Tomy shoes

<p>I bought size 10 Tomy takkies at Canal walk this past Saturday. while still in the store I asked the lady working on the floor if I can use the fitting room for my Son to change into new pair of Tomy takkies. she checked my bag and slip and let me use the fitting room. On monday my son put the same shoes to school and after school when I was helping him to untie the shoe laces, I noticed that the shoes looked different. The one has silver shoe lace ring and the other one is black. The shoe laces material is also different material. I do not know how these shoes were paired together and attached with a string if the are not the same. I went to Foschini at Golden acre and I was told to address this matter with canal walk store. I called Canal walk store and my call was transfered to kids floor but there was no response. So basically I couldn't get hold of anyone who can assist me. I need a refund for the shoes or exchange.Please help.</p>
