Disgusting quality and waste of money

On 4 December 2018 I bought two identical pairs of black Jeggings from PNP in morning glen. I was forced to pop out from work as the same pair I had on had ripped. Today I put on both the other pairs and find that these have ripped or pulled apart as well. These are pants that haven’t been worn a lot and haven’t even faded. The quality is absolutely terrible if three pairs in less than a year have pulled apart or ripped like this. I’m horrified that I’ve bought the more expensive jeggings and this has happened. I love pnp clothing but this has put me off completely.
