Poor customer service

I recently made a purchase from the Converse website. Delivery went smoothly no issues. However, the shoes did not fit me and hence I logged an exchange. The return process also went smoothly and I got confirmation that my shoes had been returned. I received this email confirmation on 19 August 2025. It is now 25 August 2025 and I have yet to receive a refund or a new pair of shoes in the correct size. In fact, it was never even asked what size shoe I would like or any kind of process I should follow here. With neither shoes or my money I am at a loss here. I have sent an email to their customer service line and yet I have received no response, this was 3 days ago. The website is very slow and terrible to navigate as a user which adds to the frustration. Unfortunately will not be buying from Converse again through their website and would rather go through a 3rd party like Superbalist/Bash where the delivery/returns process I have never had an issue with. Incredibly frustrated since the return is closed on my profile on the website. Anyways, will I get my money back?
