No proper customs receipt from FedEx and all feels like a ****

I’m supposed to receive a parcel from Shein via FedEx. I have not received any link for my customs or any email from FedEx showing me exactly how much I need to pay for my customs. Instead I get a WhatsApp message from the supposed driver who sends me a picture of my receipt. How does FedEx not send me any information from at least their finance department or the department that handles customs matters but send the delivery driver to text me a picture of the “invoice” on WhatsApp? How do I confirm if this is correct? Is that not the reason why FedEx has so many ****s? Who handles this and what FedEx’s procedures when it comes to customs and receipts? Now the driver calls me to say I have your parcel and kindly confirm if you have made customs payment, of which I ask him why am I only hearing about customs from him and not directly from FedEx? No email, no link from FedEx whatsoever of which he replies FedEx is current overwhelmed and going through a lot internally that’s why even simple things like proper receipts are forgotten. WOW!! I’m truly shocked by this company and this is the reason why innocent people are getting ****med using the FedEx name because the company is not well organised. He says he drives around with a speed point if I haven’t made customs we will swipe when he gets to my place. FedEx honestly needs to pull up their socks and Shein need to stop using FedEx
