Have you received any update from Sunrise support about what the actual issue is? If not, I’d strongly suggest calling them directly and asking for a clear status update and estimated resolution time. Since it’s already been 7+ days, this should be escalated as a priority case. Also, check if the Connect Box 3 Fibre https //192.168.l.l shows any specific error lights (LOS, red LED, etc.). That can sometimes indicate whether it’s a line issue or something on their side.
