Bad Customer Service,No feedback to Customer

went into the Cape Gate branch to exchange a pair of Sandles my son got for his Bday in January. Unfortunately they were too big for him so i had to put them away.I forgot about the shoes and now they are too small.I asked the Manager if i can exchange the pair for another pair, and she said no i couldn't because i do not have a receipt for the shoe.I fully understand the exchange policy but Its unfortunate that i do not have it as it was a gift.They advise me now that i must now go ask my Friend when? where? and how the item was paid so that they can be able to assist me.REALLY NOW?I am just wanting to exchange the Item a, it is still in the original packaging, unworn and totally resalable. I.I asked them for the Area Mangers number but they refused to give me his number saying that he will advise the same thing. I took the matter to the customer service where Leonard, contacted me within 2days wanting my contact numbers to resolve the matter.I advised that i am best contactable on Email as Im not always available on my cellphone.That was 11 days ago!I have since not heard a word from Leonard and i am extremely DISGUSTED, i feel that the Group does not take their customer seriou
