********** upgrades

Somebody **********ly upgraded on my account and vodacom refuses to reverse the double payment taken by debit order saying they have a recording that says I requested an upgrade through some other company telephonically that isn't even Vodacom. WHAT!??? Except it definitely wasn't me. How is this even possible? I am absolutely furious and WILL NEVER USE VODACOM AGAIN. I have been a loyal Vodacom customer for years, its disgusting how I am now being treated when they have committed *****. NEVER ALLOW THEM TO PUT A DEBIT ORDER ON YOUR ACCOUNT. THEY CANNOT BE TRUSTED.
