Hi Del,
welcome to SayNoTo0870
I have had a look around for some kind of Number for this API issue from Thomson.. I have found in the FAQ Section -
Tompson FAQ it suggests you can go into your local branch OR call that number... so it that another option?
Otherwise a search for Thompson Fly
Here shows a few alternative numbers which are all Geographic maybe see if one can put you through.. lie and say the number does not work....
Let us know how you get on though, sorry I couldn't help more..
