Picked up a pack of Gluten Free bread products in ASDA today - best by date of 11.01.11 - big patch of green mold on them

Handed them to a young lady on the staff and when i told her about the mold she tried to hand them back and said "It is not my Department".
I refused them, but in afterthought I should have bought them and then asked a Manager what they were prepared to do about them - I will the next time it happens.
But the attitude of the young lady(?)??????
