Cellphone Contract

People just be careful when signing a cellphone contract with Vodacom, l've just received a sms stating that my Smart XL Subscription will increase from R699 to R739 from the 1st of May which was never explained to me personally when the contract was taken out. I urged you to be careful because its not fair that you pay for something that wasn't explain to you from the word go, all they interesting is to get you to sign that contract. Its a lot of ******** that people get ********** for something that was not explain to you. Glen
