MOULD RESIDUE ON HAT

On 05-05-2015 my Mom asked me to buy a Fascinator (hat) on her behalf as she is going to attend a wedding tomorrow. I bought the hat for R500 and it was covered in a clear plastic so I could not realise that it had mould residue on it. On arrival home my mother noticed it and said I should go back to get a refund or exchange. I went back and spoke to a lady by the name of Gloria who said she explained to me that there are no refunds. No she did not explain anything like that to me because if she did I shouldn't have bought it. She went to their store room to get another hat but even that one had the same problem and I was not left with any other alternative but asked for a refund. Their manager was not around at the time but came in and told me \there are no refunds even exchanges". This is **************** and violation of my rights. """
