VIOLATION DOES NOT STOP REGARDING DATA USAGE WITH VODACOM

<p>I am very disappointed in Vodacom, according to you, my data usage of 1GB in 2-4 days was correct...although I have been using the same amount of data (1GB) in 3-4 weeks for years now for exactly the same purposes I use it now. You did refund me 1GB for the "inconvenience" caused that lasted me surprisingly 11 days....I bought another 1GB 31.07.2017 19h00 at night and depleted 02.08.2017.....I DID MAKE SURE I FOLLOWED THE INSTRUCTIONS YOU SEND TO ME FOR LOWER DATA USAGE. EVERYTHING WAS IN PLACE....AS I SAY I HAVE BEEN USING 1GB IN3-4 WEEKS FOR YEARS NOW WITH THESE PRECAUTION SETTINGS!!!!! PLEASE ADVISE ME WHICH APP IS ALL OF THE SUDDEN USING ALL OF MY DATA AFTER USING THESE SAME APPS FOR YEARS NOW!!!</p>
