Poor customer service

Good day, I would like to exchange my shoes from a size 5 to a 4.5. I called your customer service and was informed that exchanges must be done in a physical store. Using the “find a store” feature on your website, I was given two options within my radius: A store in Braamfontein – when I went there, I found that it is permanently closed, which means the information on your website is outdated. Shelf Life in Rosebank – I called the number listed on your site but there was no answer. I eventually found another number on Google and spoke to a Shelf Life representative, who informed me that they cannot assist with an exchange because I purchased the shoes online from Adidas, not from their store. I do not want a refund, I only want to exchange the size. I’ve heard many negative experiences about delays with Adidas refunds. Today I went to The Glen as google still shows that the Glen mall has adidas store, to my surprise I was told that the store has been closed. I’m wasting time and money running around like a headless chicken looking for non existence adidas stores. It’s the worst online store I have bought in my entire existence
