متن اصلی - انگلیسی - after we got in coontact

after we got in contact with several authorities regarding requested matter we unfortunately have to inform you that the customs certificate you got cannot be confirmed by our chamber of commerce.
Whether we would send it to the embassy in order to get it signed, we would have to give it to other authorities before.

As this whole procedure would take lots of time and costs we would like to ask you to find out it there is any other possible solution in this matter.

Thank you in advance.
