Lost Coins From Mbappe Sale

I sold gold Mbappe (at a massive loss) and overnight, the coin balance was lower, as in the entirety of the Mbappe sale was reversed coins wise. 

I don't know what to do. I was at 520k before I went to bed (post Mbappe sale) and woke up to being at like.. 231k. (Coins taken away). I have no idea why, and if EA's even looking at this, I'd like some form of compensation.
