Since several weeks, I am not being able to checking my old invoices, because every time when I log into the O2 web service, it says:
“Excuse me
Due to technical problems, your data cannot be loaded at the moment. Please try again later.
Your O 2 team”
For me, the logging into the website is more comfortable than the mobile app. THe login works on the mobile app but not the web app.
Could O2 customer service please help me with it.

Dear
welcome to our community. 
Have you already deleted the cookies and cache in your browser and then tried again? Or have you tried a completely new browser with which you have not yet logged in to My o2?
I did some adjustments and was able to download your invoices. Please see if it works now.
Kind regards,
Andrea
The problem is resolved now. Thank you for your help.
