Punished for Migrating to more Expensive Price Pla

My contract started January of this year, on the 'Un'Smart L plan to which the fee changed from R499 to the new fee of R529 or whatever amount it is.<br> <br> The issue, I have is that I requested to move to the Red Package R999 which my iPhone is an extra fee R50 is then paid for the phone. The problem is that I must now suffer for the remaining of my contract by paying R300 for my iPhone and not the R50 as advertised on their webpage.<br> <br> The Consumer Protection Act stipulates that all consumers have the right to be charged the same fee.
