Give him your bitcoin address so that he may refund you. You're lucky this time that he has responded you on this thread and is willing to refund your amount. Get the lesson learnt from this trade and do not repeat such mistakes in the future.
We can't really sure he may refund to OP because promise is still promise, until OP confirm he already got back his funds. Just like this guy Loan Default (CryptoVzla) promising to pay on May 22,2020 and now he's gone.But I hope I'm wrong here, just my opinion.
well he blocked me in discord, and i cant send PM here cuz im new , not sure how i send him my btc address , i will wait for his reply
It's suspicious, how come he's block you on discord 
If you don't mind, you can post your address in this topic.
