Edgards Shelley torn underwear worn only once!!!

I bought a packet of Shelly Hi-cut 5 pack panties on Monday 29 December 2025. I wore the first one on 30th December and by the end of the day the elastic separated from the cloth and it now has holes. I then wore the 2nd one and the same thing happened. This means that these are disposable panties since you only wear them once and they are torn. I am highly disappointed and the sad part is that I still have 3 more that I am not even keen on wearing because they will do the same and I cant even return them for a refund.
