STX transaction failed to arrive at Binance exchange

So I sent 100 STX today from Blockchain wallet to Binance exchange without a memo, because there was no room to include it. And it’s been up to 3hrs, my coins hasn’t arrived yet. Any idea what I should do, so it can go through or be reversed?

In this case, best thing you can do is, you will have to contact the exchange, it is completely at their discretion what to do.
I’d give them as much evidence as possible that this money came from you. They might not give you the money, it depends, or it might take some time to decide.

I’m surprised there was no room to include the memo though, usually just some digits of numbers, should have room to include. Which wallet did you use to send this STX?
Tx cannot be reversed. : (
