Swindled, scammed (6)
I believe the answer is:
conned
I believe this clue is a double definition.
'swindled' is the first definition.
('con' can be a synonym of 'swindle')
'scammed' is the second definition.
(I've seen this in another clue)
(Other definitions for conned that I've seen before include "Studied carefully" , "Taken in, tricked" , "Deceived" , "Studied; cheated" .)
