I usually don't go in on EA but this got me heated

For Christmas I bought my son a PS4 and madden because he always played my solos for me and he loves football, mind you my son is 6, two days ago he accidentally put his 93 upgradeable snowbeast mariota into a token set and didn't tell me about it because he thought I would get angry. So I got on EA support on a quest to try to get his card back. After being in a chat with a guy who couldn't type in full English for over a hour they decided to "ease the pain" by granting my sons account with a gold premium pack! Talk about a slap in the face..the worst part was after needing all the details to look into the account and saying that they were gonna help the guy told me that they had no way of giving cards back that were accidentally put into sets which I know is garbage..I'm very unsatisfied right now and have a upset little guy who worked hard to upgrade that card...and for anyone that is gonna say don't let your kid do sets on their own I don't usually and have told him no auction of sets without my help but he has watched me play madden for years and thinks he knows what he's doing and it's impossible to watch him while he's playing at all times..sorry for this ramble I'm just very upset right now
