How to contact O2

[Ford1]

For 2 days I've been unable to contact O2.  I am flight crew. There is an outstanding amount of £5, yes £5 and they've blocked my account.  I've even paid this amount and the account remains blocked. I've tried calling from a landline today and the 0800 numbers are not connected from the landline in another country.  Does anyone have a telephone number that I can contact O2 on ?
