Misleading customers

They gave calenders which for March is buy ANY ticket and get a free ticket. Just wasted petrol money going through to canal walk as they refuse to give it and said it's not for ANY ticket!!! Misleading the public!!! I'm VERY ****ed off now!! They seem to get you like that so you forced to buy the tickets but I didn't bother!!! Becoming a waste of time & money coming to numetro!!!
