Just out of interest, did you email them or fill in their returns form:
http://www.evanscycles.com/return_messages/new
"Once you have completed and submitted the online returns form you will receive an email confirmation with an Evans Cycles returns department address label with your unique return order number. This should be printed out and attached to your packaged item."
Did you not receive your email with your returns label?
All the options are here.

Never had an issue with them. Hope yours get sorted soon.
