Did you put your score in the computer as well as handing in your card ? Most systems have a function to count scores for players entering and not recording a score as NR. Most committees will not reconcile the actual cards returned as we have computers to save work like that. I'd check with the comp secretary as something is clearly wrong.
Although this practice happens, under the Rules of Golf a player should not be disqualified or have an NR for that competition if he fails to enter scores onto a computer.....
