Poor service for mail box

After being with Vodacom for more than 15 years, all of a sudden my voicemail box was no longer functioning. I dialed the mailbox and a voice mentioned that I had no mailbox. I followed the instructions to activate a mailbox, and was informed that it would take approximately 24 hour. I'ts been now approximately 24 weeks and I'm still waiting. Come on Vodacom, is this how you treat your loyal customers? You just cancel mailboxes and then don't respond at all when the instructions are being followed. Maybe I'm not \big enough"for you to worry about. If it's the case"
