Anyway, I have tried doing these stuffs before, of course!
So, I bought the domain and hosting plans ad then I'm ready to install the site.. Then, when all is done I refresh the page and it always says DNS errors. That's then I realize I should have wait for my boss.
So, I contacted the contact support of GoDaddy because I want to cancel all my purchase and request for a refund. After few minutes, I receive a response from their team and give me instructions on how to cancel the items and after it they just ask for call-in PIN and I give it ASAP.. So this morning, I saw their email about the refund and when I logged-in on my PayPal account, I saw my money back!
I'm just so impressed of GoDaddy's contact support. They're very fast on taking actions. I sure will purchase there again when I build another site I'm planning!
(Good thing the site I was creating for my client is finally solve and done! Thank God!)
