****** 9 Gb plus more

<p>with the purchace of a new Android phone in October 2016 I received 5 Gb of data. to my amazement it was valid, not for one month but till 2020! then I received another 4 or more, not sure why, so I had just over 9 Gb. I only use 250 Mb per month so this would last me for ages. Early on 1st Jan 2017 I received a message that all my data was depleted. I was away from home so bought 250 Mb to tide me over. Two days later my 250 Mb was also ******. then some airtime also disappeared, about R150. The Vodacom shop was friendly but unhelpfull. I only update on WiFi and I checked my apps data useage and nothing used more than 25 Mb in the last 30 days. Who stole my 9 Gb plus ther rest?</p>
