media release changes by papers

I sent Media releases out for Harbour Theatre's current production recently, only to find that one of the 'local' community papers had added two lines to it, totally changing what I had written and given away the ending of the play! I rang them only to be offered an apology, but please keep sending them information!
My question is, has this happened to anyone else? Can the papers change our media releases so much without consulting me?
We need the publicity, but I'm loath to trust this paper again if they feel free to change to content of a media release so much.
I'd appreciate any comments about this subject, Thank you.
