Pure fraude, hang up imidaitely Company named Weekendjegenieten is a website only They dont produce any of the travels as mentioned in their telophone call. Their only target is to produce bills! Standard phrase in that phonecall: thanks for filling in our questionaire. I cant remember but if so this was anly ment to get my mail adress and phone number and sell it to spammers. They only produce bills and threaten to cash them in. Just bing or google for "fraudes" like Stideris (stichting derdengelden incasso service) The companies they pretend to do the financials for (see www.stideris.com) do not exist and all have an addres in oficces which are empty and for rent.
