First and foremost, don't worry, if a deposit was sent to the address indicated on your interface, we will find it!
Few points:
Depending on network speeds crypto deposits may take anywhere between 1min - 10min to land. If it has been longer, do check on the blockchain explorers to see the progress of the transaction.
Please double check that you have sent the correct coin on the correct network to the correct address. Personally I have made this mistake more times than I can count where I sent USDT to an ETH wallet on other sites and was surprised after 5mins have passed and the deposit didn't land. So please learn from me and check twice.
In any case, if it has been longer than let's say 15min please reach out to our support and they will be more than happy to assist!
