in English it is commonly called "fee" not commission.
if you don't want to share the TX ID with us that is fine, go to blockchain.info and paste the transaction ID in the search bar and look at the bottom right section and find a field called "Fee per byte" if in front of it says a number which is smaller than 200 then your transaction had a small fee and that is why it is stuck.
