Location of Data

I renewed my contract in February, so it becomes effective from March 2015, from then until this month Vodacom does not allocate my Data as per contract. I have to phone every month for it to be allocated and demand that they reimburse me with airtime that has been used for Data, on the 07/04/2015 I called customer service and they have lodged a complaint and sent me a sms that said \problem and feedback will be given in 24 hours"it has been 24 hours and nothing has been done or said to me. I phone back today at 09:00 the responded is they will get back to me. VODACOM HAS BECOME A VERY POOR SERVICE PROVIDER IN THE RECENT YEARS AND VERY EXPENSIVE. As this problem has happened to me on my previous contract renewal. """
