POOR SERVICE FROM VODACOM

Account Number NA022607 - Kindly note I have posted reviews on Hello Peter previously regarding an issue I experienced with Vodacom whereby I have been billed after my contract was cancelled. A consultant contacted me and advised me the charges will be reversed and the account will be on a nil balance, however I was later contacted by a debt collection department demanding the balance outstanding, I have now been told by my bank that my credit score has been affected due to Vodacom listing my balance outstanding on the Bureau. This is absolutely ridiculous. The amount listed is R345.86???? Please can someone attend to this matter urgently, failing which I wil l proceed further with this matter as this is affecting my credit vetting.
