Not sure if I'm in the right place for this query but...I bought a T-shirt a few weeks back, washed it for the first time and followed the washing instructions like I always do, and it's come out all misshapen and with a small hole in the front. It's only H&M so wasn't at all expensive, but I really liked it and want to take it back. Problem is...haven't got a receipt, so would I just be wasting my time?
