*****elent account opened at MTN under my name - no support

In March 2022 I received a notification on my FNB app that MTN wanted to initiate a debit order. I didn't open an account with MTN, so I declined. This happened 3 times. I then see in my credit score months later that an account was opened in my name in March 2022 without my consent or knowledge and since then it has affected my credit score. I have tried numerous times to resolve this, but no feedback. I have asked for the paperwork completed on the contract as well as a copy of the ID used and Proof of address, but this has not been shared at all. This ***** is unacceptable!
