If for any reason you want to get in contact with O2, then you need only go to their Contact Us page here http://www.o2.co.uk/contactus. Even though they’re as big as they are, O2 is still very much accommodating to their customers, offering to provide the best way of communicating with them based on the customers’ specific needs. One of the available ways to contact them on this page is through live chat with a customer service representative. Just click on the “Chat to us online” option, provide your name, number and nature of problem or concern and you’ll be connected to a chat representative.

If you want, instead of chatting with a representative, you can also read their many helpful guides and support articles here http://www.o2.co.uk/help. If you can’t find the solutions to the particular problem you are facing, then you can post your concern on their online community here http://community.o2.co.uk/ and wait for an O2 guru or a helpful O2 customer to offer you some advice.

If you prefer, you can even book a call back from their O2 gurus here http://guru.force.com/O2GuruSiteRedirectCallCenter for assistance – this way, the time and date will be convenient for you.

If a phone call is just not enough for you and would want to converse face-to-face with another human, then you can book to meet up with an O2 guru in store here http://guru.force.com/O2DeskStoreLocator.

If physically visiting one of their brick and mortar establishment is not convenient, then you can even tweet them at @O2 and use the hashtag #O2guru. You can also reach them on Facebook at https://www.facebook.com/O2UK.

For complaints, you can visit their complaint page here http://www.o2.co.uk/how-to-complain or you can just call 202 from your O2 mobile if you’re a Pay Monthly customer, 4445 if you’re a Pay & Go customer, 0800 230 0202 if your concern is about landline and broadband connection in your home and 8002 if you’re a business customer.
