Quite a few things really. However, your first port of call should be your club.
Advise your club secretary, competition secretary if its a league table or result that is not correct. They will contact the Association. Please be very clear with the details, especially in relation to competitions. Ensure you have age group, division and type of competition, mixed or girls/ladies/mens so that there is no possibility that someone will misunderstand your query. Do not contact our office directly
