Gems Error em.ext.10027

I purchased gems, and this is the message I received. "em.ext.10027" 

I did not get the gems, but I checked PayPal, and it shows the transaction pending.

I checked how to resolve the issues, and was told to clear history, cache, and cookies. I did that and tried to make a purchase again, only to get the same message and another pending transaction on PayPal.

This needs to be resolved quickly, not only because of the money being tied up, but because I cannot finish badges you put time limits on.

Thank you
