This was weeks ago already, can you still do the credit card thing?
The only thing I edited on my post was the title, from Horizon Hobbies to Horizon Hobby.
Check with your CC company. Mine allow 90 days to contest a transaction and it doesn't matter if you have paid the statement on which the charge appeared. Call HH tomorrow and tell a supervisor what you feel forced to do and why. Get his name and include it in your letter you enclose with the Rx you are returning. I still think you should be able to solve this. You are sending back a new un-opened Rx.
