Itemised billing (Case ***)

I have logged a case at the support centre in Pietermaritzburg. I followed up on the progress on 20 March, battled my way through the automated call centre and 5 calls later was told that my itemised billing was missing and they will retrieve a backup and send it to me. Today on 27 March I still have not received it, contacted the call centre, battled my way through the automated voice options just to be told I must speak to Legal and get stuck in a dead end as the options available don't have any relation to my question as my account has been fully settled. Your service stic****!
