Open my suspended SIM card now!!!

MTN sent me a mail 15th February that I was owing them money that I was unaware bounced on my account.

Mind you I’ve already paid them 12th February. They have suspended my SIM card and I’ve requested multiple times that it is unblocked.

They still sent me a mail saying a owe them. Someone call me urgently to sort out this mess!

My account number: BA*** Call me on : ***
