Hi,

I am trying to schedule a GMAT test. Previously when I went to payment page, the transaction failed 4 times since my card was not eligible for international transactions. Now, when I try paying using a different card, it throws the following error:

""Block Error
We're sorry, there is a problem with your GMAT account which requires you to speak with customer care. Please visit www.mba.com/contact to find the appropriate phone number.""

Could somebody explain what'a happening here?
Thanks!

I dropped an email to [email protected] but haven't received any response. When I try calling customer support India number, it says "this number does not exist". Can you direct me to the correct number please. The slots in my available area are filling up very quickly, and I need to make an appointment urgently. Will be very grateful if you can help provide a resolution.

Hi,

I am also experiencing problems while registering for GMAT Exam. After some unsuccessful attempts to pay for the exam it now shows "Block Error-We're sorry, there is a problem with your GMAT account which requires you to speak with customer care. Please visit www.mba.com/contact to find the appropriate phone number.".
I have mailed my issue as well to mba.com and have tried calling up in the Asia Pacific Region Customer Service for the same, but no one is attending my call. Kindly resolve this issue.
