DISGRUNTLED CUSTOMER

Changed my debit order details mid-may and my bank notified Vodacom of the switching. Vodacom debited my new account on the 25th of May ( after updating my banking details). on the 25th of June Vodacom decided to debit my old account( God knows why) and the debit order obviously returned , I got notifications that I am now owing and must also pay a penalty fee for the returned debit order. When I called Vodacom I spoke to Anele who hung up on me(please also give me feedback on that), called again and spoke to Muhle who tried to assist, spoke to a supervisor by the name of Risha who was beyond useless. I called now after getting a confirmation from my bank that Vodacom did debit from my new account last month and spoke to Zodwa who told me about Vodacom policies regarding debit orders etc ( who tried to assist to her ability). Now my services will be interupted because Vodacom did not debit the correct account , or I must cater for a double debit on the 25th of July ( which is not even an option) . Why must Iget penalised for Vodacom's error??

I want Vodacom to absorb the premium which they failed to successfully collect from my new account and start debiting me my monthly single premium from the 25th of July and from the correct account.If this is not met please cancel my contract. ungratfull Vodacom, been with you forever and for the first debit order that returns you sending me notification of which this whole situation is due to your error and incompetency......
