Holes in Pajamas

My girlfriend and myself bought new pajamas from Woolworths a few weeks back. After the first few days before even washing my girl friend's pajama top just started to fray and a hole formed, after a few more days more holes started to appear. She literally only wears this at night before we go to bed. My pajama top on the other hand started to form holes as well after the first wash or two. I have always bought my pajamas from Woolworths and have not seen this on any of the other pajamas that I have from them that I have owned for years now. This is absolutely shocking, I contacted their support with photos but have received no response. Looks like Woolworths quality standards have dropped.
