...used my name n address! he used my name and address when ordering some rubbish from the internet.. can i get in trouble even though i had no idea about it??

thanks.. and yes, he will pay for this!
but surely i can not be persecuted by anyone, there is no proof, anyone could have put in my address?

your both in hot water. being IN POSSESSION of it is bad.
obviously you are an accomplice to this.

you need to change this on your credit report, get it and letthem know whats going on then report your dumb ## "friend" before something happens with you.
