They look the same but are actually not the same

I have seen on numerous ocassions the following advertisement with its headline as "Say NO to Plastic Bags Compaign" appearing on the front page of a popular national English daily.

The first sentence reads, 'Take part in the "Say NO To Plastic Bags" campaign and do your part in saving the environment.'

The headline appears to be calling readers to say no to Plastic Bags Compaign (without elaborating on the compaign); but the first sentence in its first part is urging people to take part in the compaign to say no to Plastic Bags.

The headline should have been "Say NO to Plastic Bags" Compaign in order to be consistent to convey the real theme.
