תרגום - פורטוגזית-אנגלית - Ola, senhor David. Ja mandei o dinheiro pelos...

Original form of translation:
Hello, Mr. David.
I have already sent the money in an envelope for the mail.
I have sent the money in an envelope because the transfer was very expensive.
I hope you understand. Please await a couple of days.
Thank you very much and excuse for any inconvenience.

The only thing I´d correct would be "please wait for a few more days" since the original text says: "Por favor aguarde mais uns dias." (meaning that the person has already waited for X days and is being requested to wait some more)

IDEM

The transference would be very expensive?
