Dreadful. Quick to accept the order then leaves till last minute. He merely fed me back what I told him and, basically, did nothing but waste my time. At the end of the order, when he'd done almost nothing, my website stuck and I couldn't do anything from cpanel so I had to suspend the account. Luckily...
