DATA NOT AVAILABLE ON MY UPGRADE.

In April 2016 I did an upgrade on my cellphone. I did receive 2 phones and was told that one will be uploaded with R200 every month and the other phone will be uploaded with 500mb. As I have WI FI at home I did not check the balance of the date before I needed it on the 10th of May 2016. When I wanted to use the data given to me there was nothing available. I called Vodacom and they informed me that 568mb showed on their system. I said my phone shows 0mb. After many phone calls and going to telepage this problem still has not been resolved. When I phoned vodacom on Thursday 12 May 2016 they told me the data has been depleated. I said I wanted proof because I have proof on my phone that my data usage with vodacom only shows 685kb. The person at Vodacom said they will e-mail me the proof. Up to today I have not received any e-mail from Vodacom.
