*********** call center and accounts staff...account still not up to date

I'm now sick and tired of these *********** people in the call center sending me from pillar to post like a idiot and using my own airtime. i have aid my arrears on my account in full and one months installment ahead for the month of October WHY....WHY is my account still showing a arrears balance and also why is it still with a external collector MBD when it should be back with direct axis and up to date. I want a call back ASAP and updated statement with a letter stating i am no longer in arrears. If this is not done i will take the Legal route here i will need all my call recordings from MBD requested by YOU....and my last call to direct axis were i have been sent from pillar to post i'm very Peed off right now
