Mtn

I am struggling with Mtn. I missed my payments during lockdown 3 months before I could pay up my account. After lockdown I settled and I had a stable income. I went to follow up on my account and I was told it has been handed over. They can not tell me where my account is and therefore I am unable to pay the balance of R1580. I've called the call centre and went into their store many times and they can not assist me. I don't know where to pay the account. This is *****.
