Well it's now the 23rd Sept and I hadn't heard anything more after posting on the http://my.ttesports.com/ website (not even an email acknowledging the submission although I did get a pop-up box at the time saying it was submitted successfully), so I've re-logged it even though now I'm over the 2 year warranty as it was purchased on the 18th Sept 2015 on-line (probably received it a few days later).
I must say that the website is pretty poorly designed in that you log in but can't see any previous tickets logged or any communication etc and you can't even see/edit your profile information or see what products you've registereed or anything. Under the member section, the only thing available is to log out.
