Never renewing any contract again

I've been a Vodacom customer since 1995. A call center agent called me to upgrade 2 of my numbers, I told her to phone my wife as it is the number that she is using, so she can confirm which phone she wants. She called my wife, confirmed with her that her number is upgrading, she chose a phone, and the agent said that there is another number due for upgrade, told her it is my son's number and that he doesn't need a big contract so she suggested that he gets 1gb for R69 a month, she told the agent to just confirm with me.. so I've got the call back, she confirmed the upgrade for my wife's phone. Didn't agree on taking the R69 one for my son, said I will decide still. Got the phone a few days later and noticed that the upgrade sms's went to my sons phone and not to my wife. Went to vodacom instore, heard that my son's number was upgraded to the R69 contract which I didn't agree on, and that an alternative sim card that we got extra from one of the other contracts, was upgraded and that my wife's number is not upgraded. Now they say my wife contract is only due in a months time, and that we need to send the phone back, it will be credited and we can get the phone back on her number once it is due for upgrade. So now my wife needs to be without a phone for a month because of the mess up that they made on the numbers. So they do not even have to call me back to upgrade any of these numbers as I am cancelling all my contracts with Vodacom once due for service. I will move to another network provided.
