MTN and empty promises!!

I have a contract with Mtn and they load my airtime and data every 17th of the month. Yersteday received an sms to say my data and airtime has been loaded but i could not go on the internet(insufficient data/aortime)<br> <br> i then called the mtn customer service and i was told i am not the only one and that the problem will be resolved by midnight yesterday. i called in again this morning asking when will this be resolved and they said they on it and everything should be fine within the next few hours. i am very angry because the MTN agent told me this will be resolved soon and nothing has happened and when i tried loading airtime today before i could even call the airtime is exhausted, how??<br> <br> i am really Frustrated because i cant even call nor check emails using my phone.<br> <br> i might aswell use prepaid and not contract
