Worse than government *******

Ticket no. ***. You people are like those that stole the R500 billion. My January bill was R236 as I am suing the 19 hours package. My phone then went for repairs, so I haven't been using my simcard from the 1st of February till the 18th. On the 19th, my phone came back and I started to use my simcard again. Now yesterday the 20th, I streamed about three 28mins episodes on DStv app from 18:00pm till 18:45pm. I always check my Rain app so I don't go above my limit, by streaming for 45mins, you people are charging me more than R250!! How the fudge is that possible? I abused that simcard in Jan yet only paid R236, I streamed for 45mins during peak and now I owe R270? I'm super annoyed and I'm planning on cancelling my simcard. I should have read the reviews before purchasing from you guys. All I know for certain?, is that my billing is incorrect!! With a 1gig data from Cell C, I can stream about 5 28mins episodes and still have some data left!! How can I have reached my R250 5gig limit from rain within 45mins? I WANT THAT ERROR FIXED!
