Utterly disappointed

I am a loyal customer of Truworths who literally spends thousands of rands every month. My account speaks for itself. I am always up to date with my payments often paying much more than the required installment. I bought a top for my mum and sister in February as I thought it would be a nice gift for Mothers Day. Was afraid it would be sold out by then so bought it and kept it safely away. I took it out to gift it to them on mothday only to find all the sequins have come loose. Needless to say, i could not give it to them. Went to the Westwood store and explained my story to the manager explaining to her that the tops had never been worn and still had their tags and stickers on. She said that she could not accept it as it was more than 30 days. The bottom line is that these tops are still brand new, and the fact that these sequins have fallen off means that the quality is very poor. I can understand if these tops had been worn but they have not. My understanding of the CPA isthat a customer has the right to return something that is defective within 6 months of purchase. It must be reiterated that the items are still brand new. I have now spent R800 on 2 items that cannot be used. This is a drop in the ocean for Truworths considering the amt of money i spend. Is this how you reward your customers for their loyalty Truworths?????
