I like many others hadn't realised that credits expire when your package expires, i. E. e you have to keep on paying a monthly fee to get access to the credits you have bought.
When you contact customer services you get a very smug reply pointing to a paragraph in a massive legal disclaimer that states this is the case.
Well done, one-nil to Fotolia and their robust legal agreement but in the process they've forgotten about customer service and lost a customer.
Please don't waste your money.
