Cannot avoid paying handling fee twice by Envato

I recently purchased 6 months support for an item and added a new theme also to my basket, the system made me pay for both separately so I got billed twice for the handling fee which states it is per order and not per item. I tried adding both to the basket but it wouldn’t let me.

Please process my refund!
