DATA ******* BY CELL C

i recently renewed my contract with cell c after 24months of paying them, with a promise that they would load 40GB, 20GB daytime data and 20GB night time data! but since my renewal im getting 8025MB of daytime data all the time and ive never missed a payment. CELL C is **** and they are taking their clients for fools!! i want out of this contract as all they sell u is pipe dreams
