As I wrote yesterday I went to the post office and use the post EMS service. Cheaper than Wester Union. I own money to him no longer than 10 days. My mistake was to move to the North without repay him back. He just wanted wise as he has not a Thai account. I told him to ask the manager of the hotel where he stay for his bank account or to any shop that send or receive money. But he refused to do and he wants only wise. As I cannot use wise between a Thai and foreign account, I sign up to deemoney as someone suggested, but they said it will take around 48 hours to activate the profile. And he insisted that he wants go and report me. At the end, as wrote, EMS was the solution. The envelope should reach him tomorrow, sent yesterday.
