Banoffee pie

Hi
Does anyone know where I can buy condensed milk to make banoffee pie ?? Purchased some Nestles milk in Carrefour and boiled it for nearly 3 hours and it was not set .. so I'm assuming its not the same as the UK product . Can anyone advise please .
Many thabks

Most of the stuff here is terrible, but you may be lucky in Giant or other larger supermarkets.

I'm still trying to find double cream for my beef stroganoff, but after all these years I've decided to strog off the idea.
