Bro,
1. Were you the one that manually entered the balance in local currency? If you made an error, they have the real statement, so they should be able to see the difference right?
2. Did you do the funds conversion or was it done by them? If you did, they will clear it and manually convert.
maybe send a LOE stating that you made an error in the amount you wrote down and give them the correct amount. They can use your statement to verify.
If this is what you have sent in your email, sorry you might just have to wait.
Haven't heard of anyone who called them successfully.
Good luck bro
