It does become an interesting issue when one can not use a random teleport port because there are no open spots!
That begs the question, If one has spent money to aquire said item (random teleport) and it has no functionabilty, no trade in or replacement option, well is it then a consumer fraud issue? You buy something it don't work, can't return or trade it in,
Logic would seem to be there is an issue with such a set of circumstances.
