Check here Guide: How can I sort out my network issues?  or Guide: Is the network down for me or everyone? 

Also have a look on https://status.o2.co.uk  and see if there are any issues where you work.   and download the my network app, to report issues.

But beware that coverage is not guaranteed in any location
