Contract Cancellation

Three of my cell phone contracts ended in November 2020. I have been trying to cancel these 3 of my Vodacom Contracts since November 2020 but only one number was cancelled. I phoned on the 16th of November for the first time, to cancel the 3 numbers, one was processed for cancellation. I phoned again on the 8th of January 2021 to do a follow up on the cancellation as I am still getting billed for the 2. I was told that an email will be send to the cancellation department to process the cancellation and give me a credit for not cancelling the contracts as requested. Nothing Happened. I phoned again on the 18th of January 2020, again the same story with no cancellation of these 2 contracts. I am not very happy with the service I have received from Vodacom as today I will be phoning for the 4th time to cancel 2 contracts. In future, I will not be renewing any of my other contracts with Vodacom, I am going to move over to another service provider, if this is the way that Vodacom wants to do business.
