Sorry, can't scan the letter.
I repeated at all times that I nor anyone in my household had done the downloading or uploading as that is true.
I remained polite at all times.
I contacted my MP, Watchdog and Which. Which wrote to DL on my behalf.
I answered all letters with any information I could.
I told them I no longer used a wireless connection because of someone else piggybacking and have gone back to cable. I don't need wireless as I am the only person using a computer in our house
The letter I've received today states that due to the evidence I have provided (there wasn't any) they have decided not to proceed. Then I got a lecture from them about securing my connection.
Hope that helps

Just an after thought - anyone who has the letter asking for router details and an explanation as to how it could have happened should reply with the information and they might get a nice surprise too
