Deliberate Delay caused a loss on my business services and they refuse to compensate me

They sent me a defective product, I lodged a replacement within an hour of receiving the defective light ring , then delayed my replacement for 2 weeks of which by the way I am a make up artist, I needed the light ring for Saturday courses , I have made a loss of over R500+ for the past 3 saturdays over their deliberate delay. I have requested an urgent delivery on which the original payment was made on the 27th of june , damaged product was delivered 2 july ,I lodged a replacement 2 july. It was confirmed 5 july only to be told that I will be given the replacement 25 july. i have begged them to reschedule to earlier so I can get my light ring early , I need it for my classes and I can't afford to miss another Saturday instead they gave me run arounds busy apologizing while deliberately delaying the delivery time , I want my refund and a compensation for the loss my business accumulated the past 3 saturdays

They are refusing to compensate instead sending apologies and hiding behind emails
