We don't have internet connection since last night

Hi @Maurizzio and welcome to our forum.

I'm sorry to hear your connection hasn't been working. 😕

If it hasn't been solved yet, then the first thing I'd advise you to do is check if there are any network malfunctions in your area. 
If that's not the case, then the next step is calling us on 0800-0402. Say that you don't have any services, and you should be connected to one of my colleagues eventually. 

We’re available 24/7 for malfunctions, so hopefully that way it's fixed soon!
