Hello,
Today I renew my older subscription (paypal payment is still pending).
Some time later I decided to upgrade from Basic Membership to Pro.
On page Account > Subscription clicked the Upgrade button. On the confirm payment page i see this:
Regular Price 29.90
Unutilized amount of previous subscription (-) 8.82
Discount (Google+) (-) 1.00
Amount Payable € 20.08
But the Support wrote in forum:
"you will pay the difference of plans price (of the remaining time)"
Basic price was €19.90. The price of Pro is €29.90. The different is: €10.
If my calculation is good, than I must pay 29.90 - 19.90 = €10.
This isn't so? Why should I pay €20.08?
