De***** by Call Centre Agent - No feedback from Vodacom

I was phoned by a Vodacom call center agent about 2 months ago regarding a migration on my 4 x lines with Vodacom. The agent promised me numerous times that I will save money however after the following billing month my account went up by R500. I phoned Vodacom when I received the new billing, after explaining to the complaints agent / Customer care they said they will review the phone call between me and the agent promising to reduce my monthly bill. She said Mikayla that they will give me feedback in 10 days. No feedback after a month.

I will cancel all my contract as they expire with Vodacom. Really disappointing after more than years with Vodacom.
