Complaint on a new contract

<p>I took out a new contract on the 21st dec 2016 with I store in centurion mall. The contact promised by vodacom comes with a once off 10gigs of data for 30days. Upon me phoning vodacom because some settings needed to. Be changed last year they informed me that the data will be available from the 1st Jan 2017. Today (2nd Jan) I was on the phone with the vodacom call center for over 2 hours and also being cut off a few times and recieved a lot of attitude from the staff on the line and was told I need to sort this issue with the I store. I am paying vodacom over a R1000 a month and from next month I will be paying over R2000 and my query cannot be resolved. So vodacom just takes and provides no service. Who must help me.............</p>
