3rd Party Data Plan contract

<p>I was contacted by a 3rd party mentioning how they making data cheaper and if I would like more data I said yes because who wouldn't want cheaper data. I was running some errands so my focus was not there, so apparently I agreed to 24 month contract when the lady over the phone said it was 12months. So now I'm having trouble trying to cancel this contract and they say I will have to pay something like R4000. There was a 14 day cancellation period that I missed when I called after but how must you know that when they don't even send you paper documents to say what you agreed to and actions to take to cancel. They should not allow this to happen because these people know exactly how to target you on the phone, this is absolutely wrong of companies to do this and get individuals to get money from people who are just getting by each month. </p>
