Not updating my Transunion Credit report correctly

I have a Tablet contract with Vodacom through Smartcom and I have been paying them but this month on my ITC Transunion it incorrectly shows that I am in arrears for 30 days. On the 25th of July I also received a call from Vodacom saying they did not receive my R99.00 premiums for May and June & I asked the consultant how is that possible because there is money in my account and I asked the agent to deduct urgently from my bank. The agent told me Vodacom cannot deduct and that from now on I must make my own payment due to 1 deduction that bounced. This was very confusing, how can you stop deducting from my bank without notifying me or at least advise me to make manual payment?? It was not my fault , You decided to stop deducting & you don’t use tracker and beside I had money in my account. Listening to the voice recording will really help. Please clear my name on ITC Transunion because it messes up my profile.
