Wrong destination tag entered

[Frankthetank]

So I sent 11500 xrp from gatehub to Bithumb yesterday I put in the right address but wrong digit in the transaction tag gatehub finally got back to me saying it was sent and irreversible and to contact Bithumb , so I contact Bithumb still with no reply giving the the correct destination tag I wonder if this is something they can easily do since I have all the info or am I gonna get the run around looking for my coin I’ve emailed them called them Facebook messaged them it’s only been a day but I’m stressing any Input would be appreachiated since I am new to cryptos

thanks
