我經銀行轉帳左錢俾人,但我唔知佢地扯,點去小額錢債追?

actually you can contact the bank, see whether they can contact that guy. If this transfer was done by the bank staff and bring your loss, the bank should have helped you to dun for the money. have you called him? you better contact him first to accommodate.

BTW, address seems meaningless if you already got his contact number, and the a/c num is unique so if you wanna sue him for not returning you money, they are able to trace his address and information.

首先把你的銀行記綠copy一份 給法庭,記住要把文件攪好少少, 你可以寄掛號到佢公司 , 只要係通知到佢咁就可以了
