No customer service and a broken website!!!!

I have been trying to book a package with Kulula for 2 days. The website never allows me to go the payment page and continually resets. Twice when I got through it ended in an authentication error that provides no actual error information. I emailed Kulula two times at 6am and 8 am. All I got was a response saying they will get back to me and no response in 12 hours. I called the call center and asked to get details emailed to me with a reference number for a booking. From 9am still no response 13 hours later!!!<br> What must I do to get services and assistance. Such poor customer service!!!
