**** to & Mislead

I don't know what made me look over my account in detail this evening, but I did. My contract increased, however I never agreed to this. I remember receiving an SMS/Email about this about 6 months ago and I went straight into the Vodacom shop in Bayside Tableview and spoke to a staff member their who advised me that this doesn't apply to me as I have signed a 24 month contract. I asked him is he sure and he advised me that he will contact the call centre and double check. He called them and they also advised him over the phone that this won't apply to me as I signed a contract and will only effect me once I renew my contract. I'm like most people out there who don't really look at their account in details, but I'm disgusted in that I was **** to and when you call into the call centre to complain about this they don't have any compassion or sense of morale, they just don't care. I'm shocked and don't know what to say about this...
