I am surprised that people are surprised at his behavior as @The Pharmacist left feedback almost three years ago, stating that he is late with payments and zero fucks given attitude about it, so it's not something new but a thing he consistently does yet people rushed to be hired by him for that Eloncoin crap. Then we laugh at bounty hunters that are getting scammed and mistreated all the time...

@tranthidung since he is more than 2 months late with the payment, as as you said no reply is unacceptable, maybe its time  for more drastic measures as some said that he only sorts stuff out after being pressured, and couple of negative tags doesn't seem like its doing the trick.
