How this troubleshooting works
A deposit that hasn't arrived usually comes down to a handful of things: it's still waiting on confirmations, you picked the wrong network (it went to a different chain), you skipped a memo you needed, the amount was below the minimum deposit and never credited, or you mixed up an exchange's internal transfer with an on-chain deposit. Start by using the block explorer to confirm whether the transaction actually made it on-chain and whether it went to the address Binance gave you, then follow the branches down. That's usually enough to narrow it to one or two causes.
To see how long a normal deposit takes, read how long deposits take. To check the rough confirmation counts per chain, use the confirmations lookup.
It doesn't go online, doesn't check the real status of your transaction, doesn't file an appeal for you, and doesn't promise you'll get funds back by following it. All it does is help you think it through and point you to the right self-service page. The block explorer and Binance are what actually decide.
