Failure to provide statements

Hello,<br> <br> i have been struggling to get MTN to send me a detailed statement for an account that i owe and also to confirm my total outstanding balance.<br> <br> I have emailed your service center since November 2015 and have yet to receive what i asked for.<br> <br> I was told to call MTN from the number in question, but i no longer have the sim card and informed your staff of this, but no response from them or your legal department. Not a single call or email.
