Bad service

<p>Hi my MTN number has been discontinued,i tried logging the request on twitter i got no responce,i then tried calling from another number,then the call gets cut (twice),,i then find aother number ********** ,i called and a lady tried to assist,i explained to the lady that my line has been cut off,i asked her why,she said that my account is in areas,i told the lady i made a cash payment,she said the payment was recieved,I asked why my line is diconnected,she told me that there was no payment made in January 2012. When i first recieved my statement i made a call to MTN to ask if I am in Areas,they said no i get billed in areas, i dont understand why after 5 years my account gets suspended without notification or a statement saying im in arease,please can this be sorted out URGENTLY</p>
