02 have been ripping me off for months: part 1

I keep having to come to the Library to use the internet, because 02 are saying that I have used all my data on my phone.  I have a sim only contract which gives me 2 gigs of data for the internet.   I have found that 02 have said every month that I have run out of data.   I have found this to be quite surprising, as I have previously been told by Vodafone, that if I just go on the internet, and use email, then 2 gigs of data should be plenty to cover my needs. Yesterday, I phoned up 02 to question the fact that I was supposed to have used up all my data in 24 days.  I told the 02 customer service person that there was no way that I had used all this data.  I had mostly only been on the internet, and read my emails, and had hardly been on You Tube at all.  He told me that if the figure was wrong, there must be a virus on my phone causing the wrong figure to be given and that it was nothing to do with 02. He also told me that a 5 minute high definition video took up 60 megabytes of data. (there are 1000 megabytes in a gig)  I told him that I had only watched about five 2-3 minute videos on you tube, because I had wanted to make sure that I did not use up all of my data.  I have mostly only been on the internet, I have sent only about two emails, and I have watched at the most 15 minutes worth of videos on You Tube. This would total at the most to 180 megabytes.  My phone was saying that I had used 651 megabytes.

Today, I went into the 02 shop to speak to the 02 Guru about the issue with my phone.  He showed me a chart with what you get for 2 gigs of data.  For 2 gigs of data you get: 20 hours streaming music; you can send/receive 1500 emails; you can surf the web for 15 hours; you can make 90 social media posts; you get 3 hours of streaming videos, and you can download 23 apps/games/songs.  Well, things really don't add up.  At the rate that the 02 customer service guy gave for watching videos, 3 hours of streaming videos would use up 2160 megabytes of data (2.16 gigs), without leaving any data left for all the other things that you can do for 2 gigs worth of data.  I think that I have been lied to. The Guru also told me that a virus on the phone would not affect the data usage, that the phone has nothing to do with it, and that I have no virus on the phone.  I told the Guru that I thought that 02 were messing me about and lying to me. And I told him that I knew why.  After some discussion, the Guru asked me why- and I decided to take up the courage to tell him why, and about all the different things that all the big corporations had been doing to me.  The Guru remembered me from before, when I went to see him about the issue of emails not coming to my phone until many hours after they had been sent; something that he found to be most unusual. I am glad to say that he actually took me seriously and was quite sympathetic. It is good to know that not everyone is corrupt that work for these big companies, and that you can find some people that you can trust. Unfortunately, I have 5 months left in my contract with 02.  I will wait and see what they do to me for next month.
