The cache is not at the published coordinates.
The published co-ordinates will take you to the location of this 'Fine Pair'. Unfortunately, the phone box here has seen better days, having been the victim of considerable abuse, and one can only wonder how long it is likely to remain in place.
These phone boxes, designed by Sir Giles Gilbert Scott in the 1920's, have become collectors’ items and an example of things quintessentially English. It is sad that those who vandalise them cannot see their beauty.
For more information on the phone boxes, see the Wikipedia entry Red Telephone Box.
