Not on the best deal
My gripe with the various organisations saying the public could save £X million a year by swapping to the cheapest provider misses the important point that I may not want to be with the cheapest provider. For instance for broadband my cheapest provider would be Talk Talk, but I consider the extra few pounds a month I pay not to be with them money well spent.
It's similar to saying we could save billions by everyone buying a Dacia Sandero rather than an actual car.
On the flip side, they don't appear to be suggesting mobile providers contact you by SMS when you're at the end of your fixed term, which I would have thought would be the best way to guarantee getting in touch.
