the worst network provider with misleading Ads

I received an sms that says I should recharge and get 10X my airtime. I recharged with 25 but only got 100 airtime. the sms even said the airtime would last for 14 days but when I received the airtime it stated that it will be valid for 3 days. <br> <br> just how do you do your math. This exactly why I keep that number off, its because of the empty promises and terrible network coverage we experience.<br> <br> I wonder why I even waste my money you don't deserve my cent. <br> <br> I should just port that number to other networks.
