Very bad service

This is not the first time that I have had problems with this store when returning items that are faulty or bad quality. It clearly states on the back of the slip that you have 120 days to return a faulty item. Management refuse to give refunds or take the faulty items back and their excuse is that it has been worn or is out of the 30 day period. When I point out the 120 day period they say that doesn't matter and I must contact head office if I'm not happy. The management are rude, have no customer service skills, are in breach of the consumer protection act and have no regard for causing a scene and being disrespectful!
