Can't complete purchase - Avada extended support

Got an email offering extended Avada support. Tried to make the purchase three times but your system won’t let me.

Keep getting this message:
Sorry, we couldn’t complete your purchase.
Just click the button below and we will try again.
We just need to finalize the purchase; you will not be charged again.
