VANS SOUTH AFRICA - Refund Issue

I have had an unpleasant experience with Vans. I bought a pair of Vans on the 24th of March and returned them on the 25th of March and asked for a refund, i still have not received my refund (31 May 2024). I have been in the store 3 times and have had multiple calls with the store manager as well as two of the store sales assistants. I have been told it is a problem with my virtual card but my virtual card and normal card have the same digits. I have spoken to my bank where they confirmed they have not received a refund on their side and that my virtual card has nothing to do with it. I have also spoken to head office where they can’t help much as it is not an online purchase but they will escalate it with the store. The message that I am continuously being told by the store themselves is that they are working on it then they give a date by when it will be done and that date continuously comes and goes with no result. I am done waiting for my refund, i want answers and my money that is owed to me.
