I was working and suddenly my DSL went off and I noticed that the DSL light in my fritzbox was not lit. I tried all troubleshooting steps (checking the wired connections, restarting my modem and checking DSL interference) but no luck. I called Hotline and set up a appointment for technician visit and noone showed up on the day and time mentioned. when called hotline they initially said that technician definitely visit the day mentioned and after couple of hours when called, they said the technician will visit another day. by that time it will be a week for me without internet and it is extremely necessary in this situation considering a lot of people are working form home due to corona. It is frustrating how each agent can convey a different information without considering the customers consequences.
