Bad service

I took out a contract for my Son for a handset with Sim card with benefits. The benefits were loaded in the 1st month and thereafter I could not access those benefits. I've called cell c in the past 2 months and have spoken to different consultants that have not been able to assist me. I pay Cell c every month for a service that I cannot use so this means that you are just ripping me off. I want this resolved urgently
