Changes in Widgets not showing on site?

HI,
I have made some changes to a tel number in the 'call us' txt option in a number of widgets. The problem is the changes are not showing on the site? Also i have altered the number in the footer and that has not changed either? Can you pls check the site and find out why these changes are not showing on the front end of the site? The tel number should be 01286 880808 for the Wales address.
