I can say I swear, I promise, I confirm didn't say him anything bad thing on him and then he scold bad word at me. My site become useless without he help and also I don't have my password for the site. It like paying $99 for nothing, I'm the one angry and he said good that I'm angry. So what to do now, I please him, I sorry him and the end he ask for more money. Ok fine, I pay it for help few step to complete, then suddenly he change he mind and he said waste his time. I really really don't know why he angry with me. He also said I wasting his time, crazy keep ask him for help. Of course I'm crazy, I already paid $99 and it like getting nothing.
