Hi Emma
Sorry to hear you are in the predicament - I completely understand that paying for a service you are not using is far from ideal. I know that the situation for our billing teams is changing day to day, but as far as I am aware we are not currently chasing anyone up for bills, and your services should not be ceased if you do not pay (however the payment will be required eventually).
Now, I am not a member of one of our billing teams myself - so I may not be fully up to date with the current process, so my advice would be to give them a call to discuss the bills to see if anything can be done. You can get them directly on 0845 600 6156 or you can contact them via livechat.
Regards
Ryan
