Accountability time: No "maybe" about it.. You didn't follow the instructions and then you say it didn't work for you. Well of course not. You never gave it a chance.
This is like buying a nailgun and then ignoring all safety warnings, you use it like a hammer and accidentally shoot your kneecap with it. So you call it defective and return it to the store, telling everyone hammers work better for you. Okay, maybe that's a strained analogy.
