Material Mart refuse to refund skew material V

On the 3rd of Aug i bought Place mat material 10 sets. It cost me R550 after cutting i realized the material is scew i took it to them and complaint, there answer was stretch the material till it fits. After days of struggling Tuesday 1 Sept i went back and asked for my money back as the fabric is still skew. Manager said that he will be in hospital on Wednesday i must come today Thursday 3 Sept.<br> <br> I went and to my surprise they refuse to give my money back as my 30 days already expired yesterday. They had a bad attitude towards me. <br> Im very upset and i want my money back... never to say the time i lost struggling.
