FedEx did not deliver the envelop
FedEx did not deliver the envelop. Twice recently. Alwais same adress. Several Apostilles correct. Two we did not receive and need to pay extra 75$ to receive something that we already pay for.

Reply from One Source Process
Hello Carlos,
I have reviewed this situation with my staff and I'm going to refund you the additional $75 for the FedEx shipping. We did redo the entire apostille free of charge, but we have had a policy in place from the beginning that we are not responsible for FedEx shipments due to the fact that they are a 3rd party provider that we have zero control over.
However, this is a situation that happens so rarely and due to your review bringing this to my attention, I have informed my staff to not rebill for the shipping charges as well for any future instances of lost documents.
Please accept my sincere apologies for the frustration.
Best,
Brandon Yoshimura
CEO, One Source Process
Very quick and extremely easy.

Prompt service and response
Prompt service and response. I sent a document from Athens, Greece, to one source process for an apostille, and within two weeks, I had the document back in Athens. Excellent service.

Outstanding service
Needed an apostille on short notice and there was no way I could get to NYC to shepherd it through. One Source got the document back to me in just three days (one day to FedEx it to New York, one day for them to do the work, and one day to FedEx it back to me). Outstanding!

Peace of mind
Peace of mind. I could have done the requests myself for less money, but I wanted the peace of mind that comes from letting the experts do their thing.

One source was a life saver for me!
One source was a life saver for me! It was easy, it took them no longer than they said and cheap compared to what they wanted to charge me here in Brazil. Thank you!
