Waiting for a wire transfer!! Why it took so long??

Hi guys, I just wanna share my experience to you about bank wire transfer. There is this guy who like to send me money from the USA to Singapore by wire transfer from the bank of america. I had been waiting for this for almost 6 days, but I haven’t received anything from him. Do you know guys why does it take so long to recieve money from the US to Singapore? What’s the reason behind this? I don’t know, if anyone of you know the answer, pls leave the comment on my blog below here. Thank you for reading my blog and have a nice day! :)
