Hello, did you ever get to Uruguay? I sent a shipping container from the UK in October 2020 and it's still in the port of Montevideo accruing a storage charge of US$14 per day. It has now exceeded the value of the contents. My customs agent said there was nothing that could be done until I got to Uruguay but I have been here since September 2021. I also sent an extra suitcase by Fedex. That got held up at customs who wanted US$260. I found a big cheese at the freight terminal and put it to him that if I had struggled with a third suitcase on my flight, it would have been accompanied luggage. He agreed and it got through with charges of about US$50 saying that it was Fedex who scribbled something on the Air Way Bill that raised those charges.
