Hi everyone, new costumer here!
Yesterday I received the Quick Start package(sent to the wrong address BTW...)and I was excited to connect it, besides I had been told the previous tenant had Virgin Media... but I found out the wall socket is branded differently and the cable can't fit...actually there's a cable sticking out of the wall, is it related somewhat?:

I hope to get help as soon as possible, it's been weeks without internet...
Thank you in advance!
