Amusing email from MR today about how they've reduced their phone rates - they 'will provide significant savings to all of our calling customers!', so I check the only country I'm interested in, South Africa, and lo and behold, cell phone rates have gone from 25c/min to 30 and landline rates have tripled to (also) 30c/min.
(yes I am being selective but that doesn't sound like a lower calling rate to me)
