Saying NO to overseas call centres

According to this article, there used to be a website called http://www.saynottooverseascallcentres.com/ but this site seems gone.

Although many companies have moved away from Indian call centres, too many remain. Right now, top of my hit list are Three and Virgin Trains.

Does anyone know of a good list of companies that DON’T use Indian call centres, so I can choose to use ONLY these companies?
