Woolwich will not send me a termination statement

I have been trying since 2013 to get a final statement from the Woolwich for my two mortgages on my London apartment when I remortgaged directly with Barclays. I have written called repeatedly by phone to no avail. I cannot believe that they cannot deal with this. To make things worse, the mortgages now do not show on their system when you call their customer line, and so they refer me to go to a branch of Barclays and ask them to assist me, but I am in South Africa so this is a non starter. Can someone from Woolwich contact me and get things going here?
