I have now my first bill and it has not been reduced even though I had to wait a week after I got the router to actually be able to use it. So not only did I have to pay extra to get more data thanks to Virgin Media messing up, I also now have to pay for Internet I could not use for a week. On top of that the claimed 512mb is so far off what it actually is, I'm averaging under 100mb per second.
Truly terrible quality of both the interner service and customer service. I had been told I would have my first bill reduced due to being sent the wrong power cable, yet it turns out that was a lie.
