Reliance Trends — socks

I really loved the collection of socks from team spirit and i bought 3 pairs yesterday along with 4 pairs of shoes from ajio i have an issue regarding with the socks as due to the magnetic pin you guys put over it or the item was damaged i don't know but when i wore and roam for 10 minutes and when i removed them i saw it was torn. How can this happen. I need satisfactory response as i need a replace.
