Shunned, having raised cost unexpectedly (10)
I believe the answer is:
ostracised
'shunned' is the definition.
(I've seen this before)
'raised cost unexpectedly' is the wordplay.
'unexpectedly' indicates anagramming the letters.
'raised'+'cost'='raisedcost'
'raisedcost' is an anagram of 'OSTRACISED'.
'having' acts as a link.
(Other definitions for ostracised that I've seen before include "banished?" , "excluded from society" , "shunned" , "Sent to Coventry" , "out in the cold" .)
