I have a charge for a telephone call to USA number I do not recognise. Can you explore?

You will need to check your phone dialler history, @Dot2 - as you can see it, I am assuming you already have access to your bills in your MyO2. You can also use a search engine to see info about the number.
Otherwise contact O2, Guide: How to find help & contact O2 has all the ways.
Good luck!
