False Information

On the 8th of November 2019 I was phoned by one of Vodacoms call centre agents. I was told they can migrate my contract, i will have more data, more airtime, more sms and it will be cheaper than what i am currently paying. I repeatedly confirmed with the lady what my monthly installment will be. She said yes every time. She told me i will not get a new device, it is just my contract that is changing. End of November i got a shocking account from them. I phoned and was told they gave me all the extras from the 8th of November, so that is why i am paying extra. From end of December my account will be right. End of December came, got the same account. I phoned again to query my account and was told they will investigate. I said to them i am being charged for a handset but did not get a new handset. I was told you get charged extra for a handset, wasn't the handset always included in the contract????? I asked to be migrated back to my old contract as i can't afford R300 more a month on my contract. I was told i can't migrate back because my old contract is not available on migration. On the 16th of December 2018 i upgraded my contract, took a contract i can afford, got a new handset. Now they phoned with a "special", false information about the migration, no new handset and now i am paying for something i didn't even get. Apparently they listened to the recording, didn't say i gave false info about what i was told about the migration but they can't change anything. "Sorry you have to pay R300 a month extra for the remainder of your contract". I can only cancel my contract next year February but i am DEFINITELY moving to another network!! I won't be ****med into one of Vodacoms "specials" again!!
