Limit of 5 Items Per Month and Customs Delays on AliExpress

I recently tried AliExpress in the hopes of taking advantage of their offer to bring in five items per month without paying any customs duty. I ordered four items in September, three on September 5th, and one on September 11th. However, only one of these orders has arrived at my door, and the other two have been delayed by customs. It's very likely that I'll have the same problem when the remaining item arrives. To make matters worse, I am helpless and without recourse. There is no one to address my concerns or guide me through this difficult situation. I also ran into an issue where a third-party agency demanded additional taxes, which only added to the confusion. My experience with AliExpress has been far from pleasant, and I'm left perplexed and disappointed by the entire process.
