I know your situation. I asked my forwarder that Why sent the original BL to you delay ?
They explained as below :
Since shipper have not pay for us for the origin Local fee. We tried to contact shipper but no one contacted us back for the charges until this morning ,and We have send the original BL to shipper this morning.
Pls note that we can’t send original BL without no payment.
I know you came Thailand last week as a result the contacted had a problem.
Don't worry about that , You can present all of documents as normal, I'll inform my Bank to accept your documents.
