I just want as many people as possible to know what you sign up to once you decide to join O2.
Long story short, I signed up for Home Broadband and Phone in October 2010. Waited 2 months, got confirmation that the starter pack was on its way and a letter with all the details (including the landline number) but the landline was never connected, the address in the system was wrong and never got updated even though I asked twice and the advisors confirmed they'd updated the details each time I asked. Needless to say we got charged the connection fee for the phone line that never got connected. When I called the helpline at the end of November the advisor told me O2 wouldn't be able to provide services since our address, let me quote, "is not in the Royal Mail database". I contacted Royal Mail immediately and received confirmation that our address was in fact in their database. Next day I spoke with the helpline again to be told that still the company wouldn't be able to provide us any service and that our contract would be cancelled in the next 2 weeks.
I came home from a holiday in January to a mailbox full of threats that our non-existent home phone and broadband would be disconnected and the details would be passed to debt collectors. We thought it was a mistake when 2 days later I received a text saying "thank you for paying your bill".
Over the course of 2 months waiting for our broadband I think I spent over 3 hours in total chatting with your helpline trying to get to the bottom of the problem.
5 minutes ago I received a text and an email stating I owe O2 £233 and some other payments and by this time I just want to never hear about you company ever again.
