REMOVE EVOLUTION BUG

yesterday i pressed remove last evolution on my cr7 evo'd card after i went to View Available Evolutions he didnt have any evolutions apart from that i didnt get a refund on the evo to use it again its a shame cause i lost the make your national hero part 1 evo which was really important and now i can find it to use it again i would like a roll back on my account to the point my card had his specific evo's on him or at least a refund on the make your national hero part 1 evo so  ican use it again
