Refusing to reimburse my money

In my introduction I went to High Line Tyres in Rustenburg yesterday next to rhomdiam place flats to do wheel alignment so it happed they didn't do wheel alignment for me.How ever I payed cash and one of the male service proovider told me to say to due to some faults in my vehicle he can't proceed with the alignment.in that case I was handed yellow paper stated that I must come within 7 days period.i return to the store the following day to the store to request my refund and I explained to them to say I need my money back they refused with my money I payed for alignment.more over that is against consumer act Nd its insabodination.
