First day of contract and glas light doesn't turn on/no wifi

I recently moved into a new apartment which has kpn fiber ready to go. I received my modem and fiber box a few days ago. Today September 5th was the starting date of my contract I connected everything and noticed that the glas light wasn’t turning on and there was no internet connection. I unplugged and re did the entire process about 5 times throughout the day and still no luck. I have looked at the status of the order on the app and there is just a grey box that sais “start met aansluiten”, when I click it it just returns me to the previous screen. I am wondering if I should try calling again or if there is anything I am able to do on my end.
