Accidentally bought wrong tank

MrConway: I might be able to save you and our customer support team some time by answering.   Unfortunately this is not something we can just reverse for you. You can ask support to reset your account to the day before you bought the AMX 30b as a one-time exception, but that means you also loose any other progress made since then. it also means that this will not be an option for you in the future.   So if that is not an option for you, you can close the ticket.   Hope I helped
