The items received from the collection event packs were taken away

I would like to warn you in advance that I wrote this message with the help of a translator.
Hello, I'm coming to the forum because tech support doesn't want to answer me properly about my problem, and if something starts to come to a solution, tech support says that it can't interact with my stuff in apex in any way.
What exactly happened? 04/03/2024 at approximately 5:25 UTC +3 time zone, I opened 2 containers of the collector's event, each worth 100 apex coins, since the first 2 containers had a 90% discount, from the first container I received the legendary collector's skin for R-301, and from the second container the legendary collector's skin for Mad Maggie and the legendary banner for the Catalyst, I was very pleased because I really wanted a skin from this event for Mad Maggie, after that I left apex and went to bed, the next day when I logged into the game I found that everything I got from these containers was taken away from me, tech support confirmed that this was a problem on their part, however they said that nothing could be done about it they can't, so they sent me to the forum, because according to them, there will be more chance of help here. Below are screenshots of what I received that day. I will be incredibly grateful for your help with this problem.
Also, if possible, I would really like @EA_cuervo to help with this problem, as I have seen that he has solved similar problems very well.
