Well since posting this I finally come across an solution thanks to an email from a deaf community member.
It was as easy as just going to teletext and pressing 888 subtitles on sky movies sky one everything ... the problem is solved.
Now I'am angry as to the fact that no NTL/Virgin Media customer service employee knew this and advised me of the matter its so annoying that this has been a problem for weeks and as I said before we were told that they do not carry the subtitles for sky channels.
This is totaly beyond me and just been a big pain in the bum
