Phantom Arrears/ BlameGame / New System?

Mystery Arrears

I have been querying an arrear amount on my MTN account for over a year and No ONE absolutely NO One in their call centre can tell be what/why the arrears amount is for. I have discussed the matter with several agents and all I need to know is what the arrears is for. It seems each agent just keeps guessing which month it's for and then proceed to ask me for proof of payment which I then duly provide and then they blame the system. Dear MTN, please provide proof of the outstanding arrears amount, if you are not able to provide proof please remove the hold on my account as I would like to shockingly still renew my contract with you. Please wake up before you lose me as a client
