Before you raise a charge back with your CC provider, you should have email correspondence with VA that includes:
- VA cancelling/moving your flight (rendered unsuitable to you) and that they are offering a travel voucher in lieu of a refund
- Your reply which is a refusal to accept anything but a full refund back to original form of payment (per ACL) - see attachment
- VA's subsequent reply of travel voucher only
You should then raise a charge back with your CC provider. Once the agent has opened the case, reference the case number(s) in your email you send to the CC provider. Include the email correspondence referred to above. For Amex, the Disputes Team are at
[email protected] and

WRT to language, everyone's circumstances are different so there's no one size fits all. But if it helps give you some ideas, I've attached something that may be useful to include wholly or dissect according to your needs. There are some closing comments at the end which you may or may not want to include depending on how you see things.
