HORRIBLE AND RUTHLESS COMPANY WHICH exaggerates default amounts on Transunion profile

Apparently i took a contract phone from MTN and due to lockdown i couldn't pay my phone because of financial crisis. I then tried to apply for rental accomodation last week and got declined because of low scoring. The company which were helping me with accomodation have send me the results from transunion and the shock of my life that the information from transunion is indicating that iam owing MTN R79500. The phone i took was a huawei P20 Lite. Where on earth does that phone worth that amount. I WILL HAVE TO TAKE THIS FURTHER AS THIS COMPANY PUBLISHING THE WRONG AMOUNT ON THE TRANSUNION PROFILE. I have contacted MTN and the answer was that i must consult Nudebt management. Iam very disappointed.
