Bad quality blouse

I bought a blouse late last year at pick n pay Blue route mall Tokai, and the quality was so terrible! I've worn it twice and it is torn and just falling apart. I paid +-R300 for this item and I emailed pnp support more than a week ago, I then emailed a different pnp support, nobody has gotten back to me about this issue. I cannot locate the receipt and I would like my money back, Id like to know what will be done about this ridiculous non-responses. I expect more from pick n pay.
