Shocking after sales service ethic

I bought a watch from The Casio Shop in South Africa and paid ZAR 3199 (Order #CAS-ORD-11037 (placed on May 19, 2014 12:04:15 PM SAST) ten years ago and over time the bezel has faded completely so that no figures are visible anymore, I requested a quote to replace the bezel only and received the ridiculous price of ZAR1780, stating "WATCH PARTS - CASE, BEZEL, DIALS & HANDS " and "The bezel comes with a case complete only" How can a reputable brand like Casio not supply individual parts and expect customers to pay for parts that do not need replacing. Despite emailing Casio MEA, they are ignoring and failed to reply. Bought my LAST Casio watch ten years ago then !!!!
