Bad Auto spares

I bought a clutch kit for a Conquest 1.6 at Ganis auto spares in middelburg (Eastdene) 259 Cowen Ntuli street on,26/01/21 @08:35 for R850. Upon realizing i bought a wrong part i then went back 27/01/21 to the shop to request a refund as i didn’t require a clutch kit anymore.Part was not used (sealed n packaged as given the day before) The staff member there was rude and also racist in saying if it were a “White owned shop like (Middas spares),i wouldn’t have returned the part,he further went on to say i should **** off out their shop. I refused to leave without my refund subsequent to that they,charged me a handling FEE of R250 and only then did i leave. Felt belittled,cheated and disgusted at their customer service.
