No joy in sorting out a ********** activity on my Vodacom account

I recently discovered that someone decided to do an upgrade on my account/line, at a Vodacom branch. Trying to have this matter sorted with Vodacom, I am just been taken from pillar to post with absolutely no joy at all. The ********** transaction took place almost over 1000km from where I reside and as to how a Vodacom consultant helped someone else with an upgrade on my line, is mind boggling.
