    “Provider went on a month long trip which I knew about. After the trip, he has not been available to me for questions. I have tried to contact him though GAF, facebook and msn. All of my messages are ignored. Highly disappointed... I had really high hopes in him after the reviews and friendship I thought we had formed.”

  • image of WebPay musaulker - Private Security Project $500.00 USD

    “Totally waste of time. Accepted the project, escrow done but Musaulker went missing without a reply for 2 weeks. Finally responded with a brief message that he was hospitalized but ready to continue the project. Gave him another chance to deliver but went missing without news again for another week. About a month lost but nothing, I repeat nothing, not a single code was deliver nor shown to indicate he started or spent any single effort. He has yet to reply to my last message over PMB and seems blocking me on MSN but actively bidding for projects to look for his next victim now. I bet he will surely reply with all his lamest excuses to justify his case but I am sure my rating here carry better weight with the experience and reputations working with dozens of GAF here. Count yourselves lucky for not having to got stuck on your project before having to rant here.”
