It is difficult and risky to actually ID an orchid from just seeing the young plant without flowers, but from your description of the flower and plant habit, I would like to venture that it is a Hexisea. For flowering this plant, I would let it grow into the 'octopus' like size and give it a rest during the dry season. Do not fertilize it much and sort of let it 'suffer' a bit to encourage flowering and not promote more vegetative growth. It prefers to hang from a slab and when in flower it can be very spectacular with either bright red or orange mini flowers. Let us see what others might suggest it is, but certainly do not junk it.
