Scam to additional content

I purchased the additional content "Forgotten Shores".
Forced to change the SD card, I had to reinstall my apps from the Amazon Cloud.
But when I launched Monument Valley, more Forgotten Shores, yet bought Amazon, with Amazon order number.
I called customer service, they reply that the additional content is lost, can not be reinstalled, I have not bought from Amazon (sic) but directly to the developer (I have proof of the direct purchase Amazon!), it is not refundable, and I only have to look elsewhere!
I said I would contact the DGCCRF (fraud control), what I will do.
Whether on the Amazon page "in app purchases" or when buying, it is nowhere mentioned that in case of relocation, additional content will be lost! This is the obvious scam.
