I ordered new internet on 14.06.2022, technician was booked with an appointment on 29.06.2022. Even after checking I wanted internet soon they dint provide early appointment.

I took leave and stayed at home as appointment told that technician may visit from 8am till 4pm. I started to call telecom customer service at 1pm they told I have time till 4pm so technician might visit by 4pm, I waited patiently and I made a call at 4:05pm and they said technician is running late and will arrive shortly by 6pm. I asked them to call the technician or provide the number to me to conform what time will they come. Unfortunately the worst service I have expirenced is with telecom because they say they cannot contact the technician who will be visiting my home and I felt they is a huge gap between there service and it's a inconvenience caused and I waited waited but the technician dint show up. 

The Wrost and s#|t service from telecom.. now I'm at home without internet from past 16 days because of telecom.. No one is helping me at customer service that is even more frustrating. Please don't buy telecom internet in berlin, Germany. Rather fo with vodafone.
