Hi, I received Hero's Call and opened it but after a while it dawned on me that there are no small cards in the set, but looking through the list of what should be in, there are supposed to be some. I live in the UK and would like to know who do I contact about this? Thanks for any help.

Contact FFG through the User Support button at bottom of page. They're pretty good about mailing out missing stuff.

You can also contact your retailer, which is faster if it works (assuming it's local bricks and mortar). Don't know about UK consumer law but if what you bought is defective/not as labelled on package, it would be routine for the retailer to replace it under basic sale of goods law in all common law jurisdictions.
