The number for Toshiba, 0844 8478944, has the number 01932 841600 in the unverified base, I have just used this geo number, and although it rang for a while,(about a minute), it was answered by Toshiba, (I think it was the switchboard), but I explained what I wanted and I was put through to sales,(not what I wanted), but was then transferred to technical, spent about 20 minutes on the phone for 5p, (1899), so this geo number can be verified.
