Atrocious poor service

I went to exchange shoes that i bought in january the stitching came off and now they can not buckle up I went in Jenica if that the name of the cashier told me EDCON has changed rules last week and they can not exchange my shoes without a receipt even if its which i believe its manufacturing fault as to how they have been torned the Manager Poulos was no help i waited long had to be called again to come see me and told me its wear and tear I asked can he define a wear and tear and manufacturing fault what is the problem he couldn't the service was disgusting ,poor and just atrocious. The shoe is with 6 months and I don't wear them everyday the Manager came with a chip on his shoulder and was not even willing to listen I am livid i feel Edgars wonderpark should explain to us upon buying things the different definitions to faults as returning things is a mission for them and their attitude needs polishing more friendly would be appreciated.
