No Caller ID by default on Contract

I recently signed a new contract with Vodacom and found that I had no caller ID enabled on my contract. I visited a Voda Store and was told that caller ID was not enabled by default and it would cost me an extra R10 per month. Out of principle, I refuse to pay a cent for a service that should be enabled by default on any cell phone contract. Other networks seem to manage to offer this service for free! I will also never sign another Vodacom contract for this reason, ever! I will also ensure that I tell everyone I know about this outrageous money-making scheme.
