Only told some details after I signed my contract

When taking out my Vodacom contract, I was told that all basic services were included in my contract. I made sure to ask of any extra charges and was told there were none and that my contract would only come to R499p/m.<br> <br> I was not told upon signing the contract that Caller ID was a \value-added"service. Which I think is rather neglectful. Besides the fact that this service is provided to all Vodacom prepaid clients free of charge - which is another thing I find funny"
