*****ulant account(A***) on my name

I am writing again to MTN, my name and reputation is destroyed. I cannot buy a house or anything because of MTN taking me to credit bureau. since January I have been going up and down begging MTN to clear my name I was told that the case is close and received a letter from a person who was doing investigation and the letter stated that the account(A***) is closed even with the external debt collectors and when I try to buy a house again all the banks rejected me they told me my account is on arrears and I went to my bank ABSA to find out why they also rejected me they told me about the MTN account that is still linked to my profile under the Experian side, what MTN did they took out my name from the bureau only but that debt is still under my name at Experian with an amount of R18000.00 . I have been going up and down and so emotionally drained having so much stress because of MTN , the sad part is that I am not even their client but I am suffering, it was easy for MTN to paint my name and its a mission for them to clear the mess. My life is hell because of MTN and I am going to hand this to the lawyer MTN must pay for this.No bank wants to give me a home loan because of this.
