Vacation Network is a scam. It's owner Linh Dinh (firstname.lastname@example.org) screws everybody....their customers, suppliers and employeees. They used to be in a location in Scottsdale AZ and failed to pay their rent and other bills there and vacated in the middle of the night.
They have hundreds of customers that canot get a vacation request. They also have more than 30 disgruntled employees that get screwed on their paychecks.
They promise gifts to go an a sales presentation then fail to deliver them. This is so wrong.
Stay away. This is a bad guy and a bad company.
