Suspending accounts without reason

At the end of February I paid a double amount on my account as my debit order did not go off at the end of Jan, so after my account was suspended for the whole of Feb, I went to 2 different Vodacom shops in George to confirm if there was anything outstanding so that I could settle it and both confirmed that my account was up to date and my phone was unlocked. Yesterday 13/03 I received an sms telling me my account is still in arrears with R292.33 and will be suspended if the amount is not paid. I contacted the call center and enquired about this to which Philemon rep**** they only got confirmation of the 1 payment that did not go through on the 3rd. I argued with him and said how is this possible that you notify me a week and a half later that the amount did not go off and now all of a sudden want to suspend my account? and how can this be when 2 shops and the call center who unblocked my phone confirmed that my account was up to date? Vodacom is the worst cellular company and I will do anything to move my account to a different supplier, but unfortunately my 2 years is not over yet. no assistance was offered I was only told it will be suspended automatically.
