Builders Warehouse ethics

I purchased a brand new Flymo from Builders in Kenilworth in Sept 19 after my old one expired after 20 years service. After 4 months the new Flymo shredded its drive belt and despite extensive search I couldn't find anyone who stocked a replacement. It seem Flymo no longer have presence in SA. Lo and behold I visited Builder in Stellenbosch this week to find they still had an identical Flymo for sale (old stock I assume). Despite knowing that parts are not available Builders still planned on selling this to an unsuspecting buyer. This is immoral and ******** in my mind
