Roomster.net should create a check box for renewal policy so no one can miss it, which authorizes roomster.net to renew billing only when the box is checked. Otherwise, SOMEONE IS GOING TO MISS IT (and I did) and roomster.net CANNOT avoid being blamed for ripping (at least some) people off. I never have imagined that I would actually get in this situation in AMERICA since in South Korea - where I spent my childhood - this kind of ripping off is punishable by law; and appearantly it is not a case in AMERICA. This is a disappointing fact to know. I thought you guys had better law system, but again, appearantly, it is not true.
I highly do not recommend this site.
