Data missing. On-going process....

<p>Here I am again. I reported that my data go missing around the 17th to the 19th of each month since October 2015. This is still a trend. Last month after a long debate Vodacome gave me my 5 gig back. Guess what? yesterdat the 19th the same happened again! It is as if they have a standing "debit order" to just TAKE it away each month. I instaled the Glassware app as they suggested to monitor data. There is no unusual activities on there. Now my question...where and why is all my data gone on the same date each month since October, and every time I must put up a fight! Clearly I must change to another provider</p> <p> </p>
