Pedros Glenwood dispute

Good day, I have been asking for a refund with Pedros for over a month now my issue hasn’t been resolved. I was on their drive through on the 22nd of April 2024 at 18:39pm when their terminal was faulty . The transaction on their side declined and on my side it went out of my account. I was informed it will do a correction with 24 hours and if not I must submit my statement for them to refund me. I emailed them my statement and spoke to their manager and till today I have not been refunded and they ignoring me when I ask for feedback.
