Hello,
The recharge options that are available vary per region. If a recharge option is no longer available then unfortunately you will not be able to use that method to recharge. You will need to use a different method. We apologize for this inconvenience.

As for your missing ingots, for all issues of this nature you will need to contact customer support via the in game ticketing platform. Here is the link.

Thanks and Have a great day!
