tried it mate, but with the fact that i couldnt use a phone that they were providing me with as it was broken!!

i was told to either take a 4th replacement of the same type of phone that had had the same fault! or pay a stupid, £400 disconnection fee!

after atleast 5hours on the phone to them and getting rather angry, they sent me a different type of phone!

dont think you're gonna have much luck im afraid!!
