Poor client service by the Puma SA V&A Waterfront flagship store

Poor client service by the Puma SA V&A Waterfront flagship store. 3 Days ago we sourced a Puma classic sneaker from their Kuilsriver Access Park store. Upin contacting them they confirmed they had the sneaker in their store. I then made my way to the V&A Waterfront flagship store with excitement as i am a puma collector and this particular sneaker would just make my collection stand out. As i met with the sales staff who was responsible for setting the shoe aside it was discovered that she accidently took the wrong shoe size from their stock room - this isn't the issue. 10 minutes in, from waiting to fa other consultant who went to fetch the correct size. Lucinda goes to the back to check up. 5 minutes later which equates the waiting of 15 minutes in the store they both come out and say they only have 1 shoe in the box. They assured me they will contact me with regards in getting the sneaker within the end of business day 2 days ago. I called all 3 days now they did not have the decency to get back to me to say still looking or anything this is truly a nightmare of a solution. I expect feedback from Puma with a solution and compensation as they cannot give a valued client such horrific client services as a leading brand and employer within the country.
