Hello!
I'm renting a flat in a house that has fiber optic connection - there's Hausanschluss in the basement. However, there's no cable to my flat. 
Since I asked house owner about getting a stable connection, I was told to get a fiber optics contract, and that there's already Telekom optics in the house, and "probably one free socket". However, after I booked a contract, it turned out that there are no free sockets (out of 4, according to what I've been told).
Now I'm not sure how things can proceed from this point, and if I should wait or cancel booking and start searching for alternatives.
Is it possible that not all bandwidth is used, and box with higher amount of ports can be installed?
Will I be offered to cover costs for expanding bandwidth? Or is there some other approach for such situations?
Sorry for using English, but my German is only B1 yet.
