Supply of airtime at the expense of accessing oti

My wife has entered into a contract with JET store by virtue of having opened an account with it which is part of the consortium composed of Edgars, Legit and Jet Mart. While she continues to pay the account, the Jet store decided to make available Vodacom airtime at the value of R100.00 on monthly basis. She was not aware that this was going to deny her access to other valuable features such as e-mails, internet, What's up and face book etc. through her cell phone.<br> <br> It is quite some time we have been phoning management of some of these shops without success because no one seems to be helpful. My wife wants to either stop this monthly R100 00 airtime while she continue to pay the instalment as agreed between her and the shop. When ever you go to Vodacom shops to ask them to install any of the listed features or services you end up being told that this is not possible until the Air time supplier provides permission.<br> <br> We are now at the messy of the JET store with no option other than only using the phone for phoning and receiving calls.<br>
