Same here , Had a problem with him few weeks ago , then his answered again to my mails and continued the coding and designing , job was almost finished, but now no news from him again since 1 week.
I guess he may have some personal problem but as he has time to connect on Wjunction he should at least take 1 min to answer our mails.Thats not the right way to do business. 6 weeks have passed since I hired him and still not completed.
