Pathetic Service delivery

After contacting Vodacom early October 2018 to change my banking details from SBSA to FNB and after having them confirm that they have - they go and bill SBSA for their bill. Why? Now after having to call a second time to query this - it appears their are two systems on which the updates need to happen and the agent who managed my call only utilised one of the two systems to update my details - I get transfered to an accounts department of sorts who updates my details to the correct one and then a debit order goes off on the right account but several days later. Now 2 weeks into the month - I am in arrears because i must pay the fee for the returned debit order which got actioned on an incorrect bank account as they did not update the details correctly!!! I Refuse! Your incompetence, poor training - does not require me to Pay you for it. Get your process sorted out - so this does not happpen in future. Probably the second worst part is hearing from the accounts manager that no confirmation can be given to me to prove that a "dispute" has been logged, as i refuse to pay the fee. And further to that no proof can be provided that Vodacom will ensure that my ITC record will not be affected negatively. Really is this the level of "Dazzling customer service" that you provide. Only excuses and nothing to prove for it.

I am disgusted and appalled by the level of service and the affect i have to endure on my ITC record due to you incompetence , lack of assurety on your process and the ability to not be able to provide written proof of how you are going to help me.
