TERRIBLE CUSTOMER SERVICE

I did my upgrade online on my Vodacom4Me account. I received a confirmation email a short while later entitled \Vodacom Upgrade Request\", wherein I was given a reference number. It also stated that I should call ***4 if I had not heard from them within 24 hours. I have done this MANY times over the last TWO WEEKS!!!! And still no response or customer service from Vodacom. Every time I call, I get pushed from pillar to post, and when I ask to speak to a Supervisor, I am told that no one is available. I am frustrated beyond words! Despite being with Vodacom since day 1 of their service here in SA, and have so far having been very happy with them, I think it could be time to migrate to another service provider. No one is taking ownership of my problem, and to be brutally honest Vodacom, that is shocking treatment of a loyal client... PLAIN BAD MANNERS AND BAD SERVICE!!"
