********** account opened at MTN in my name and MTN wont even guve feedback since August 2020 despite doing all they asked me to do

In August 2020 i was shocked to get a debit of R2300 from Mtn. I went to my bank and they informed me that MTN says i took a samsung S20. I reversed the transaction and called MTN who asked me to get an affidavit explaining what happened and i did. The consultants Matsepho Sehoshe and Mirriam Madillo Letsatsi gave me query references *** and ***. I was initially attended to Mirriam and later by Matsepho and i have initial correspondence from them via email when tbey were giving m reference numbers. After that when i call mtn they just say we see u logged a query and we ll get back to you as soon as its resolved. I tried sending emails to the consultants above but they dint even bother to reply. Now my credit score has dropped dismally and i have never missed a payment on any of my accounts. I have never been a customer of MTN. I have always used cell c. Someone opened an account with my name but no one has bothered to contact m frm MTN since August 2020. This is wrong on all levels, people are being ****** and the people who are supposed to help just keep quiet possibly because they are a syndicate de*****ing people
