Dissatisfied customer on item bought

I bought a 2 piece at Woolworths last year, i think i bought it at Mall of Africa or The Grove Mall. It was the second time I'm wearing it and i noticed that it had been torn, i thought it got bought by the iron. Today when i was washing it, as i was washing it, it tore some more and i saw it's the fabric that is faulty. I humbly request for a full refund because what I am suppose to do with an item that tores when i wash it... It is dissapointing also being a regular and loyal customer of your store, now after this i have lost confidence. I don't even have receipts of my items coz why would i keep them after so long.
