This is absolutely ridiculous

I opened a contract with Vodacom mall of the north, the consultant never informed me about the fact that for some reason you have to pay extra now for caller ID so that you will be able to see who phones you....this is ridiculous....why is this not part of your damn contract nor explained when applying for a contract.....now I can't view any of the number who phone me....and I have to pay extra to have it activated monthly.....I feel that it is not my fault their consultant do not disclose all the details and that the consultant should be held responsible for this billing.... this is not on....I am so disgusted by the service and after sales service of vodacom...I would never recommend them again.
