Now I'm trying to switch my tariff to the Big Bundle £15 and when I try to change it, it says there's an error every single time and I don't know what to do. I didn't want to waste any more money on my balance because I topped up with £15 and it took £12 for some bolt on, then I topped up with £15 again so now I have £18.</P> Fri, 03 Oct 2025 07:28:56 GMT https://community.o2.co.uk/t5/Pay-Monthly/Big-bundle/m-p/1813434#M291315 lexx 2025-10-03T07:28:56Z https://community.o2.co.uk/t5/Pay-Monthly/Big-bundle/m-p/1813438#M291316 <P><a href="https://community.o2.co.uk/t5/user/viewprofilepage/user-id/5333180">@lexx</a>&nbsp;</P><P>You need to contact O2 on 4445 or any phone&nbsp;0344 809 0222</P><P>Or via social media&nbsp;</P><P>All methods of contact are in this guide:</P><P><LI-PRODUCT title="Guide: How to find help &amp;amp; contact O2" id="Guide058"></LI-PRODUCT>&nbsp;</P><P>Best of luck.&nbsp;</P> Fri, 03 Oct 2025 07:40:27 GMT https://community.o2.co.uk/t5/Pay-Monthly/Big-bundle/m-p/1813438#M291316 Cleoriff 2025-10-03T07:40:27Z
