Deducting peak data during off-peak unlimited time

I'm on a R250 off-peak uncapped package and have a 4gig limit for peak time. So on Saturday I receive a gig limit notice at 5:42pm, which I found odd, as this was still before 6pm Upon investigation, my 4 gig peak limit was being consumed during off-peak time. I logged this with rain and was told that this does not happen. So I was ocd monitoring this on Sunday and took screen shots as evidence, forwarded this back to rain, was told that the screen shots indicate that I have a 4 Gig limit (ignoring what I had explained). Monday I took many more screenshots with the same issue occurring, sent this through, zero response, zero further feedback. These guys are *****ing peak data during unlimited time. In addition there was a point when 1.5Gig was suddenly deducted within a 12 minutes which would be impossible as the 10Mb/480p limits wouldn't allow for that. This also took me data consumption just under 1.5Gig over the 4gig limit I have set. Who knows how long this has been going on and how many customers are affected.
