Unwanted guest

I recently stayed at the Blauwberg beach hotel for a conference event my company was having. Checked into my room unpacked a few things went upon the afternoon on sunday the 7th of july. the evening i returned back to the room the bathtub was calling my name only for me to find a ****roach roaming about around the bathtub edge. i have contacted the hotel myself however no one has gotten back to me. To my knowledge i know housekeeping is done daily so how is there a ****roach, the concern i also had was any bugs coming back home and infesting my home. this is not hygenic or even sanitary. its alarming that there was even one and the size that it was, it was not a baby ****roach one that can potentially grow and infest.
