Locate sandton

I am disgusted with the service received from lacoste I bought a pair of sneakers on the 11/05/2020 less than 6 months the sneaker tore I wasn’t going to have a problem with that but a friend of mine told me that he had the same problem with the exact same sneaker so I thought this is common when it comes to that specific sneaker. I am not someone that complains but it was an expensive sneaker I paid R2295.00 for it, mind you I was with 2 other friends who bought similar sneakers at the same value I even added a hoodie for my daughter so we spent just under 10k to be getting poor quality sneakers like this. Tried calling lacoste sandton where I bought the sneaker they never answer their calls and the sneakers are in Their store gave it to the manager and he told me I should leave my number he will get back to me which he never did, I spoke to a Lizelle at head office on the 08/12/2020 who I thought would help me but to my surprise she is no longer replying to my what’s apps, she told me that I need a proof of purchase which I do not have anymore and the purchase was made cash(but honestly who keeps a proof of purchase for more than 6 months even if you do it fades) I work in Retail I know that the slip can be retrieved NO FAMILY MEMBER OF MINE WILL EVER BUY A LACOSTE ITEM EVER AGAIN, I am a very long time customer of lacoste since your ‘Bally spitz’ days
