Do i need to mention that i live in a building? Since i don't have any room number just street name and street number so i am not sure how they will send the wifi connection in my room.  

I dont want to mess with the wifi connection of my neighbors so please let me know if I should contact telekom service center and inform them about this situation.

I received the letter and it has been mentioned that they will start the connection tomorrow and no technical person will be coming.

Help is very much appreciated. 

Thank you.
