Misleading Customers (*****)

I got a call on the 8Sep advising me that my Data and Airtime contract in expiring in Nov. I advised the agent that i would like to have the same contract again. The agent promised me that i would get my R130 and 2Gb data every month. The only thing that would change is the price on the contract from R89 to R99 every month. This month came i only received my R130 airtime but havent received the 2GB data as promised. They have given me the Promotional 20GB when you renew your contract and that expired on the 8Oct. Now i have to buy data every time. I called in and they advised that the agent has mislead me on the call (They have listened to the Call from Mondo). Vodacom advised they were going to call me back as they escalated this with the upgrades department but no one has called me back to sort out this issue. This is unacceptable
