No one has the ABILITY to solve anything

Vodocom debited me twice on the 31 Dec 2015, which caused both debits to be returned unpaid and at a charge of R138 each. I called on the 17th Jan 2016 ( ref ***) and got highly frustrated with the customer 'care' center as I could not be authenticated. So I requested that the debit order stop form be sent to an email address. I have received nothing. I get calls in FEB and I can get authenticated as a client on an incorrect ID and email address. I asked them to refer back to the reference - and they are unwilling to do so and I get told I need to call them- which will help nothing as the call center won't be able to authenticate me. They are able to sent a FINAL demand letter out on an account that I am trying to get a statement on - and no one has any brains or can explain what happened. I went into my account and it tells me that I have nothing outstanding!!!! I would like proof that they have sent me a statement for Jan 2016 and follow up on WHAT THEIR ACTIONS WERE on my query ( ref number ***). I would also like the transcripts of all the calls. I would also like a comprehensive statement of my account.
