There is an official manner which you have to file a dispute with your credit card company - it is a legislated procedure to preserve your rights as a consumer. The procedure should be outlined by your credit card company on your statement or on their website - it tells you exactly the time limit to file, the address to send your disputed amount details and that the amount will be in limbo on your account until the dispute is resolved.
I believe if you have some proof from the Optum Rx website when you placed your order of the price that was shown and then filed an official dispute with your credit card company, you would have a good chance of recovery.
I don't use OptumRX but are you saying that when you place an order for an Rx with your account number/plan number that they don't give you a page confirming the order and the details like your price for it, where it is being shipped,when it will arrive, tracking info, etc.?
Now, this is the process for credit cards - NOT debit cards.
