Of course you can ask!
It sounds like nipple confusion, well, that's what it's called but they aren't really confused just find it easier with the bottle.
Keep calling the BF helplines until someone answers, tell them you're desperate and that it's really important.
Don't underplay it, the more serious it seems the quicker they'll get someone out to you.
Have you tried posting in breast&bottle-feeding on here? You might be able to find a bfc near you that will come out, I know that most people will say the same as me though, you need real life help.
Try, as Scorpio says, going to bed, keep him next to you, skin-to-skin and try hand expressing a little into his mouth when he isn't hungry, he needs to relearn to latch and won't do that when he is hungry It is perfectly possible to back to exclusive breastfeeding from now if you want to, you just need to have the strength to not use bottles as a fall back for a few days, hard, but not impossible.
My email is fan-fkn-tastic @ hotmail .co.uk btw if you need to ask me anything and i'm not here, that's also my msn instant messenger which is pretty much always on.
