How do I access my landline bills for the last 3 months as I can only see current month 's calls?

[AngiH]

I have looked at billing and can only see the previous month's activing. 

As my landline has been spoofed (According to Action Fraud) I want to check if whoever is responsibe for this, has made chargeable calls, as I believe I would  be responsible for and/or the telephone numbers dialed?  Sky Tech Dept told me yesterday that they could not help as there was no problem with line connectivity and to call the police, which I did, who in term told me to contact Action Fraud, which I did.  

I only knew there was a problem as I have an answer machine which recorded messages telling me not to call them again in very irate tones and I knew I had not made any call!!

Beware, this could happen to anyone, including whoever is reading my post.

You should be able to access the previous 12 months worth of bills so can you not see them:
