Mycelium is the worst wallet ever, I sent low priority transfers and they never confirmed so I cancelled them, then my balance dissapeared, again appeared and I only have 3$ now, and it wont sync back for 2 days, so they scammed me for money.
Going to fill report.
You haven't been scammed for anything. Just enter the Mycelium seed in another wallet and everything will reappear like magic. At the very worst it's displaying you the wrong information. A Mycelium seed will work in Coinomi and many others.
