Will never buy Woolies Jean's again!

I will never buy jean/jeggings from Woolworths again. I've bought 4 pairs and have had the same problem with each. The material comes apart and frays at the seems from the first use. My first pair I returned after a month when I noticed it wasn't just the initial stretch and actually coming apart. The second broke after 2 months. The third I no longer wear because I'm too scared it will rip in public because the seems are so compromised and the 4th riped today while I was out..IN PUBLIC!!! I brealy wore it last winter and just started wearing it again as it's getting cold. I don't have R550 every 2 months to throw down the drain. I thought that I was getting better quality at Woolworths but I'm utterly disappointed!
