Issues with calling O2 Customer Services
O2 Customer Service can be very busy at certain times of the day, so be prepared to be put into a queue before your call is answered. As there can be a very long wait, it might be easier and less expensive to call back later.
Preparing to call O2 Customer Service
Before O2 Customer Service deal with your call, you will be asked to verify your identity. This is done to ensure that no-one else is trying to access your account. To speed things up, have available all the details they may ask for’ including; telephone numbers, customer account number, contract number and your account details and any password secret answer you need to identify yourself.
Getting to talk to the right person
When contacting large enterprises, like O2, you may be asked to use your telephone keypad to select the option that you want. Listen carefully to the recorded message so that you fully understand which option is the best for your inquiry. If the options available don’t match your inquiry, either choose the option that seems most appropriate or press no key at all. With the latter, there is a chance you will be redirected to general inquiries who will find the best number for you.
Dealing with O2 Customer Service on the phone
When you talk to O2 Customer Service personnel try to explain your problems clearly so that the person dealing with your inquiry can give you as much help as possible. If you are making a complaint about something, always try to remain calm. Remember that the assistant you are talking to is only doing their job.
If you fail to get a satisfactory response from the person you are talking to or you are unsatisfied with their service, respectfully ask for their name and then ask to speak to their superior. If this doesn’t work, you may need to write to a more senior manager to raise the issue.

Other information about O2
O2 started trading under the name Cellnet in 1985 and was originally owned by BT and Securicor. It then changed its name to mmO2 in 2002 and shortly afterwards it became just O2. In 2005, O2 was bought by the Spanish company, Telefónica.
O2 has been a major sponsor of many sporting organisations, most notably the England rugby team and Arsenal. They also sponsor annual wireless festivals in Leeds and London.
Perhaps most famously, O2 became the sponsor of London’s Millennium Dome in 2007. Now called the O2 Arena, it is one of the UK’s premier entertainment venues. What many people don’t know is that O2 customers get priority tickets for events which they can purchase 48 hours before general release. Not only this, O2 customers also get to go to exclusive areas in the arena, such as the Blueroom Bar and O2 Lounge where they can change the wallpaper designs and music by sending texts.
In recent years, O2 has teamed up with the NSPCC to help protect children online. To find out more about this watch the video below.
