Shameful MTN making my life difficult with "false defaults" under my name

I am so disappointed MTN that it is making my life difficult for no reason! In Dec 2015 I reported that someone opened cellphone account **********ly (1st Dec 15 debit order of R373.25 & reference is MTN SP A******, MTN ***. I requested MTN & MTN agreed to sort this ********** under my name as soon as possible. It was opened in Cell City in Middleburg. I also sent Affidavit to customer care email as requested by Alice van der Merwe. I was checking my credit report(see attached report), I found that MTN “claimed” that I defaulted them. This has now resulted to a very poor credit score & very bad for me to apply for credit etc. I thought MTN solved this in Dec 15. I app**** for an Wi-Fi network, cell phone companies regretted me because of MTN & false default under name. My life is now miserable as I cant get wi-fi connection etc. Can you please resolve & remove the default under my name as soon as you can? I am so disappointed in how MTN really work.
