I don't think there is a chance that the result is incorrect, but you still can contact PMI to ask for more details (I am not sure if they will provide more information).
My advise to you is:
1- don't lose hope, continue your study and work till you achieve your goal.
2- analyze your results, focus on the areas where you scored less and re-study those areas.
3- use an exam simulator (Prepcast exam simulator is a very good option to consider).
4- develop a plan to execute the above and reserve your next attempt ASAP (you can easily let go if you don't have a plan and a commitment).
