anush3070, do you dispute any of the chat text that was posted? If not, it looks like you kept moving the goal posts on the time. It also looks like you were in over your head and had a friend bail you out. If the chat text is valid, you need to reduce the price as per your agreement as you were way over the agreed time frame.
If the coin is unusable, you need to provide a full refund as you didn't fulfill the original agreement.
This isn't anything new as you can read here:
https://bitcointalk.org/index.php?topic=529244.0Thanks for your involvement KWH, at this point I am chalking this up as a loss. I don't expect any refund, I am sure it is gone and spent until he can scam someone else for more. Part of the agreement was support. So even if he did fix one of the wallets last minute, I would never use it because I simply would not want to ask him for support. This is business, you can't simply move deadlines at will, let alone for a month. I asked for a refund a couple times as you can see, he would not provide it. Each and every time I had to chase him down for information. He never once offered a status update on his own. I have a couple options that I am looking into on my end to try and get some resolution. None of which I want to talk about on these forums. If the mods can close this thread that would be great. I just wanted to put the warning out, thats all.
Thanks again.
