Vodacom's shocking service

My phone was ****** on the 23rd Jan and I'm still waiting for a new phone having waited for 10 days so far. The consultant was extremely helpful until there was an issue with their insurance, (and apparently some other issue.) I left 4 messages none of which was returned. I then asked another consultant to assist and left 2 messages for her, no return call from her either. I went to the branch again (Table Bay Mall) today only to be told that there is only one person at Head Office, or wherever who can assist, he was in a meeting at the time and I was promised a return call as soon as the consultant could get hold of him and guess what......? ? I have no idea what to do now to get a new phone, It shouldn't be such a headache.
