Thanks for the heads up, I will send him another PM. If he still avoid my PM, I'll report to flippa and dispute the sale. Geezzz, I've already paid for the success fee too.
It's kinda weird that it took so long for just to secure the payment at escrow, I had a feeling that his bank account has zero cash inside it. Will try again PMing him.
BTW, how to cancel the process at Escrow?
P.s: Take my lessons guys, never trust person that newly registered at flippa and have some negative feedback. If you are going to deal with them, ask them properly via PM, make a good deal before you accept his/her bid. A contract should be a good choice or ask for upfront payment. (To ask for upfront, you have to include this on your listing, I've talked to flippa's support).
Thanks!
