If I understood the situation correctly, what happened at the end was that the guy decided to pretend that nothing happened, and the due date for the live demo was never promised, right? But you still have all the proof that he promised to deliver the product on a certain time.
It's not the first time someone has had a complaint against him, last year in November coinmixer.se left a negative feedback saying that he owed coinmixer money on work that was undelivered. So he's probably a serial scammer posing as a coder.
You just never send first to anyone you're hiring, and definitely not a jr member with no reputation. Use an escrow.
yup that is exactly what happened. and i know this is entirely my mistake. ow well.
i will earn this BTC back for sure. but he just lost an over 1 year old account. so he wont be scamming anytime soon
