your transaction size will probably be 196 bytes which makes the fee about 70,000 satoshi.
you can also make a raw unsigned transaction and sign it with the wallet if it doesn't allow you to spend the funds.
pooya that is NOT his only choice. Please refrain from giving absolute answers unless you are absolutely sure that is the only option.
He can still wait for his transaction to drop out of the mempool.
In addition, it would be nice if you did not jump to conclusions. OP already stated the receiving party "cancelled" his payment which probably means the receiving party no longer wants this payment.
With regards to the 360 sats/byte, be advised that that is not the definitive fee to get your tx mined in the next block, the recommended fees changes every transaction. Use https://bitcoinfees.21.co/ for more concrete values.
when the other party no longer wants that payment (canceled the deal) that means the only option is to double spend the funds to another address that OP controls otherwise he is going to be in a lot of trouble to contact the other party and ask them to pay back the payment (which will cost another fee) or honor the deal despite cancelling it before, as he has to do now since the transaction is confirmed.
you are correct about amount of fee though.
