I need Answers!!!

<p>I have been losing data for the past two weeks. I called Telkom call centre data department and after many calls, I was told that 'something' I was downloading was using up my data. I did tell them that I was not downloading anything and nothing had changed on my phone but that fell on deaf ears. So I switched off data on almost everything including Google. This morning I bought a 150mb, I sent two messages on Whatsapp, and rep**** to an email, checked my Facebook and put my phone on the charger . I then received an sms form Telkom notifying me that I have used 50mb, how is this f#$king possible when even Google is off and I did not even send any pictures or check any f#$8ing videos? I called and requested to speak to a Supervisor and I was put on hold for 53min and 50 seconds and i put the phone down. I will be porting my network back to Vodacom you useless F#$*&S. I want my data back and an explanation. I am tired of calling you about the same problem and being continuously put on hold till I drop the phone. </p>
