Vodacom has repeated changed my branch code

Vodacom has repeatedly changed my branch code resulting in my debit order not going through which I then have to rectify by making endless calls to the accounts call centre. The problem has repeated itself for months but Vodacom is totally unresponsive in properly rectifying the problem. The call centres appear to be hopelessly unable to rectify the problem on a permanent basis. I have been assured in numerous calls that I will be called by a supervisor and no supervisor calls. The last time this failure to process my debit order occurred my phone was \soft locked\" depriving me of service in circumstances where the failure to process the debit order was entirely Vodacom's fault. <br> I am totally dissatisfied with this failure to properly deal with complaints. Their billing department is clearly incapable of resolving this repeated failure to provide an adequate service which has caused me extreme inconvenience and frustration. It is also impossible to escalate any complaint because the call never gets put through to a superior and calls are never returned. Vodacom's call centres are hopelessly unable to provide a service which permanently solves this problem caused by Vodacom itself"
