***** MTN CONTACT

I have been a victim of identity theft to which the ********* managed to open a MTN contract in my name which I did not take out. The phone was delivered to an address that I have never used and the delivery company is investigating with the driver. MTN keeps on telling me it is with thier ***** department after I have said I realize that but the contact with two sim cards needs to be blocked as they are using those numbers to commit further ***** by opening accounts in my name and giving those numbers and then confirming my identity. The ********* are using an ID booklet copy of my ID while I have had the smart card ID for 5 years. How do they open an account so easily in my name? Why does MTN not block those number immediately and call me regarding this matter. They managed all this without me receiving one call or any other confirmation. How does this happen MTN?
