bad bad bad customers service

I'm so so disappointed in studio88 in zevenwacht Mall as I bought a airforce1 on the 14 November 2021 only too find out that the sneaker has a factory fault...the manager BRANDON said he will courier the sneaker back but too my knowledge its be standing there the whole time(I've been waiting a whole week and 3 days) as they promised to refund me or give a Another pair of sneakers but they never did...they only said I should take it on with NIKE itself as they told them it isn't a reject sneaker!!! I'm very sorry but they cant evens give me NIKE'S DETAILS BUT IT WAS SAID I should take it to nike myself..this was the most disgusting service I have ever gotten from a shop...plustens this isn't the first time such stuff happened it's just they dont follow procedures as too keep their customers happy..they made me wait...they promised they'll sort me out but never delivered to their promised!! I need something too be done please as I'm not gone let a 1400r be waisted just like this...and as for jayson his all bark with no bite when it comes too helping!!! oh and their lies!!!

oh...and I went to all another sneaker shops in zevenwacht and all of them said that sneaker has a factory fault...I need this too be sorted out please
