I'm with Virgin National on the up to 8Mbps package, and I normally get around 3Mbps, which is perfectly acceptable, and the max my phone line can take. On Thursday it took a turn for the worst and began running at 0.3Mbps, which as you probably realise, is nothing short of terrible. I contacted Virgin and apparently this was probably caused by a power surge I had last week, and the connection was supposed to return to normal in the next 3 days. I'm getting close to that time now, and there has been no change, in fact the connection is almost always stable at 0.3Mbps, which makes me think they may have imposed a sneak cap on me.
I have never heard of this problem before, so does it exist or are Virgin trying to screw me over?
