Problem with my Parcel and Contacting Support Team

I didn't want to write here, but I think I need to for advancing my case. I went to the Razer site to buy a keyboard in the day 15/07/2020 and I take the free shipping. After that occurs, it says I will receive it the 18/07/2020 and I was happy to see that... but when I saw that Fedex pointed a "exception" (Improper or missing paperwork - missing Commercial Invoice - Contact Customer service) I weren't sure about what it means. Now we're at 22/07/2020 and they have return my parcel because of that error... I tried with all my might to have it by giving them commercial invoice, but it didn't work :" I show the documents previously provided were not sufficient for our clearance team to release the goods. At this time, I would recommend to contact Razer to re-ship the parcel". I already tried to contact the support team by email at 20/07/2020 but they doesn't repond to me at all... I just need some help with my cases... and I just want to have my parcel. Thank you in advance for the help. Bernard
