Since Celcius does not offer a recovery service, I believe the only thing you can do now is to take it as a lesson.
Unfortunately, Celsius does not offer a token/coin recovery service due to the fact that this process is extremely complicated, may result in significant loss of costs, time and risk, and there is no guarantee that it will even be successful.
To avoid this situation, when transferring funds in the future, please make sure you follow these steps:
Take extra caution and double-check the address you are sending the tokens/coins to;
Verify that you are using the correct Memo ID or Destination Tag;
Make sure that the coins match the account you are transferring to.
