Mobile industry in Lebanon is scamming us

Some colleagues of mine did some calculations, and for now they did so on Alfa prepaid cards. They used to buy a card for 48$ giving them 180units, and a unit is 40 seconds, so basically 180units is 120min. Now alfa is selling cards for 25$, but in reality the person gets 22.73$, and now 1 min is 1 min, so basically the minute is now 0.39cents, and they get 63 minutes per 25$, meaning 126 minutes per 50 dollars :)

Can anyone tell me where is the reduction? Yes I get there is now a cheaper card for those who barely touch their cellular phones, but what else?

I think the reduction is most helpful for postpaid. Has anyone done the calculations for MTC?

On that note, can they start working on improving the reception, because it has become really annoying lately.
