I joined 11/30 with a subscription of 500 credits per month. I also received an initial bonus to begin with. During early to mid-December I used most of my credits to download images. However, at the one month point (December 30th), shouldn't the account have refreshed and given me my monthly 500 credits?? I was away on vacation and have returned to see that it did not - I show only 111 credits on the account with the next refresh coming on Jan 30th? I checked my downloads and show the 6 items I downloaded in early and mid-December. Nothing more. Please advise?
