Vodacom does not provide service

This is the second time I have turned to this forum within three weeks in respect of Vodacom. I have asked 3 times to speak to a senior person and my request is never granted. Vodacom stated that they will get back to me within 48 hours - it has been, at least, two weeks. The staff at the call centres and in accounts department have no idea of what they are doing and make statements that are not followed through on or actioned. They refuse to correct their mistakes and are quick to threaten the client with a credit beareau. What an utterly useless company with zero capability of servicing their clients. My first complaint was that the call centre consultants are not able to resolve the issue on my account and on this complaint I receive a response that a consultant will get back to me within 2 days, which never happened. Vodacom is a joke!!!!
