Also Sue is in the process of moving house...it is quite possible in all the kerfluffle of that the she has missed your email...or possibly her email programme has been spamming them...I have this problem with one of my US suppliers...when I use one of my emaill addys I never hear fro them as my emails go directly to their spam box.When I use my other email address i get replies within hours (allowing for the time differences!) ..... it appears their anti virus security/firewall doesnt like me!
Try a phonecall.....I am sure Sue wont mind!!
