MTN gave my number to someone else

I have been using my cellphone number on MTN for almost 20 years. I am currently on a contract which only expires next year. i have ALWAYS PAID MY ACCOUNT ON TIME BY DEBIT ORDER.<br> I went overseas with roaming activated. It worked only 2 days, then I suddenly had NO SERVICE. It was VERY INCONVENIENT TO ME while travelling abroad. When I returned I phoned my number and reached a guy in Vanderbijlpark who said that MTN gave him MY NUMBER on a new contract for his wife! he has been receiving all my messages and photos and bank info in the meantime!<br> I immediately went to Autopage who is my MTN dealer and compalined. That said that the error was on MTN's side and they gave me anew sim card to beactivated on my old number WITHIN 2-24 HOURS. IT IS MORE THAN 48HOURS LATER AND STILL NO SERVICE. <br> I WILL NOW SUE MTN FOR BREACH OF PRIVACY / INCONVENIENCE CAUSED AND PROHIBITING ME TO DO MY WORK AS I NEED MY PHONE
