Instruction to update my payments ITC

I am so disappointed with Vodacom such a big company on how you treat your customers, i have been asking for update for my account to be updated with ITC that i am not in arreas , for months i have been asking your Accounts / Legal Department to send the Instruction to ITC THAT AM NOT IN ARREAS WITH YOU , I have now put a dispute on my ITC and send through your statement but still you are not willing to confirm with ITC that indeed i am up to date , i have a similar situation with Rage of which my account was sorted and updated in 2 working days, I am so disgusted with the horrible treatment i am getting from you and regret the four years that i have been loyal to you .
