Queenspark Bad Quality

I bought a dress in March or April. A dress the same as two that I bought a year or two ago. it seamed like good buys, but the latter dress has fray material all over. I took it to the store in Secunda - which I never have a problem with, it is not the store that I am complaining about now, and it was sent to the Head Office. The Head Office returned the dress and could not refund me because I cut of the label of the dress. The hard, scratchy label, I cut off. When I took the dress from the packet in the store, it was even more frayed. I showed this to the manager and she agreed this is not right. I want a refund or credit on my account as this is not why I bought 3 dresses of the same, I thought the quality was all over good. Utterly disappointed with Queenspark Head Office
