Bank of America Credit Card Complaint

Bank of America Credit card department,

Other fee New Jersey

Hello Team, I purchased airline tickets with - worth $3000.00 using my bank of america cash rewards card on -. It attracted foreign transaction fee of $91.00. On - the transaction was cancelled by airline. I spoke to BoA associate on - asking about why transaction fee was applied and if this will be reversed if the transaction is cancelled. He said yes these fee will be reversed. When i see the account ledger today I see the base amount of $3000.00 is reversed but not the fee. I again spoke to associate today and she said they can not reverse the same. I dont understand if the service itself is not utilized why there is a fee. Thanks, -
