No Wifi/Mobile Network after I closed my account

I have an LG G3 and this morning I woke up to it not being able to connect to any kind of internet/wifi. I have tried home wifi, work wifi and my mobile data. It says "Connecting..." and then turns to "Saved". I rebooted the phone, forgot and connected again to the networkS, all with no luck.

I have had the phone for 2 years and had received an email yesterday for my final bill from my network provider, since I have requested the closure of the account (UK o2). Nothing else has happened...
