MTN advertising bundle discounts that appear to not exist.

I turned my phone on earlier and received and advertising message about calling the UK from 69c/min by buying an international calling bundle.

Problem is that you website doesn't actually show any discount for buying a bundle.. In fact I can't seem to find any discounted rate to any country for buying a bundle... see UK example below.

What is the bundled price and is there any actual benefit as I do call the UK / USA quite often, but I use a app because I previously consider cellular calls expensive - if it were actually this low I would very likely use it.
