If it's help with the handset that you want rather than an O2 issue, I suggest the you search Google for :-
Samsung Galaxy A54 help
You will get loads of good results, including text, videos etc. A good starting point is :-
Galaxy A54 5G | Samsung Support UK
https://www.samsung.com/uk/support/model/SM-A546BLGDEUB/
As @TallTrees has suggested, we'll need to know more if it is an O2 problem that you have encountered.
