I'm sorry to hear about the difficulties you're experiencing with your GMAT exam scheduling. It sounds like there has been a misunderstanding or administrative error regarding the cancellation of your exam. The first step you should take is to contact GMAT Customer Service immediately to clarify the situation. Explain that you did not initiate the cancellation and provide any relevant correspondence or documentation you have to support your case. Ask for a detailed explanation of why your exam was canceled and request that they reinstate your exam date if possible. It's important to keep all emails and any other communications you have received from the GMAT team, as this will help you provide evidence if there is any dispute. Additionally, log into your GMAT account to verify the status of your exam registration and any refund details. If the initial customer service representative cannot resolve the issue, ask to speak with a supervisor or manager, as escalating the matter can sometimes lead to a quicker resolution. You might also consider checking forums like GMAT Club or other online communities to see if others have faced similar issues and how they resolved them. If the cancellation cannot be reversed, try to reschedule the exam for the nearest available date that works for you. Staying calm and persistent in your communication can help resolve the situation more effectively. If the issue is not resolved and you believe there has been a significant error or injustice, you might consider seeking legal advice, especially if the cancellation affects your application timelines. Good luck, and I hope you can resolve this issue quickly and get back on track with your GMAT preparation.
