My Ruined T Shirt

Came back home and my Mum told me that the new T shirt I bought had bleed! I saw it and screamed. Well didnt really screamed but it was an exclamation. The green collar had bleed onto the yellow fabric. Wah lao only wore it once! We always wash our clothes in 30 deg C. When I look at the washing instructions,it said "cold water".....

I went to NTUC to buy the O2 for stain removal. Hope it works coz i really like this tee.
