On March 16, I requested a tumblr URL/Username bot. Topcoders replied to me saying he would do this for $80 and have it done with 48 hours. He added me on Skype and we worked out the deal. He kept stalling the development saying there are issues, bugs, etc. Here we are 1 month later with no bot and false explanations from him. I kindly asked for refund, he said he will refund, but never did and is now ignoring all my messages. He also keeps saying he has the bot done, which he doesn't and is just stalling more thinking I'm not going to file a dispute.
