Fedex — Unprofessional behaviour

Dear all,

I would like to file a complaint for FedEx Croatia.
I did not file a complaint to them yet but I will, I would like to inform You of their unprofessional and somewhat very rude appearance in contact with me.

I won the award on a giveaway on Instagram. The company that did the giveaway sent me the shipment via FedEx. After the shipment arrived in Croatia (my country), your workers asked me for a power of attorney for customs clearance and they received it. Also, they asked for an invoice where I immediately replied that it was a giveaway and that I didn’t have an invoice because I hadn’t paid anything. I received the answer that it is necessary that the value of the shipment is visible. I sent a new invoice that I received from the sender, but your officials also claim that it is defective. I ask again for an invoice from the sender (with whom communication is already difficult because they are not fluent English speakers) and send an invoice where the full value is visible but crossed and put a value of $ 1 because it is a prize game and again, I did not pay anything. But your officials claim again the bill is incorrect without specifying why it is incorrect, despite my questions. This communication went by email. After a week and my ignorance of what was wrong with the account, the third one I sent, I phone called the FedEx service in Croatia and the gentleman in charge of customs told me: "You really think we will believe that you won a 4x necklace, 4x earrings and 4 more gold earrings in the prize game ?! " He could also easily have told me that I was lying and no one has ever asked me for proof that it was won in a prize game, but just to report the bill is not correct without any explanation. If I hadn't called the package would have been returned and then what? Because the gentleman arbitrarily concluded on the basis of nothing that I was lying. I believe that such a large company must not allow itself such employee behavior and free will to conclude. Who gives a gentleman the right to conclude completely subjectively that I am lying because he thinks that no one does a giveaway where more than one thing is shared?

This situation will be publicly written on all forums that I can write on and I will tell everyone I know about this, you will only have a bad recommendation from me trying that no one ever uses your services again.

I have never had a similar problem with any other delivery service.
I hope you can solve this with them and unify it in some way because it is absolutely nonprofessional behavior. Especially in this time when giveaways are on daily basis on every inch of Internet (Facebook, Instagram, Twitter etc.)

Thank you and regards
