Appalling Customer service

On the 1st of December 2017 I entered into the VANS store in Mall of Africa looking for the Old skool black on black pair in a size 5. A young man by the name of Paul came up to me minutes later asking me if I was looking for anything specific. I then shared my needs as to what I was looking for in particular, he went to the back area to check if they had a pair for me only to find they didn't. I then asked Paul to check which of their branches had a pair and if it was possible to have the shoes delivered to the Mall of Africa branch, Paul agreed and he checked for me while I waited he then told me that Cresta Mall had it and the Manager who goes by the name of King said he would get me the shoes over the weekend from Cresta and that I would get my shoes on Monday the 4th of December. I left my contact details for them to communicate with me regarding the shoes of which they didn't and I decided to go there on Wednesday the 6th of December hoping to find the shoes. When I arrived at the store I found Paul there and he had not done any follow up on the shoes since he was "off" nor did he remember where he put my contact details, whilst I was still there he had forgotten that he was assisting another customer and what the customer had requested for. After attending to that customer he came back to me, the young man(Paul) was not focused, he didn't show any remorse instead he kept asking me what he should do. I asked him to call the Manager for me and the Manager said he would check other stores and would let me know by Friday the 8th latest. On Thursday the 7th Paul called me to inform me that they found the shoes at Sandton and the Manager would go and get the shoes for me over the weekend. None of the guys called me until I called today to check if the shoes have arrived and Paul the consultant told me that the shoes were not there and that there's nothing he can do. Both the consultants don't value their customers, they under estimate the customers, they lack communication amongst themselves as a team, *********** and don't respect the business. I am very upset and appalled at the level of service I received at that store.
