The problem with the fiber line is on the side of the last mile carrier - KPN Wholesale. There is no Internet for two days.
T-Mobile client service confirmed the problem and forwarded it to technical support, but they can't force technical support to act faster.
T-Mobile technical support should create a ticket for KPN Wholesale but they are just too lazy.
I've contacted KPN Wholesale, but they also cannot send an engineer without a ticket from T-Mobile.
Dear community, please help finding a way to solve this problem faster.
