Horrible package in totality sold by Pentravel

Hi. I'd like to lay a formal complaint with regards to a package I bought from Pentravel for my honeymoon. I was sent to a place (White Rose Hotel) that looked nothing like the pictures advertised. Upon arrival, we were given the incorrect room, where we mentioned that we were honeymooners, we still got a room with 2 separate beds. We were subjected to bed bug bites and an absolute lack of care or interest from the resort supp**** to me by Pentravel. We complained about this to the resort multiple times and they changed our rooms 3 times in three days with much hesitation. This in turn led to me leaving the resort earlier than expected. An 8 day holiday turned into a 3 day holiday nightmare where i had to pay extra to accommodate the earlier flights. As opposed to Pentravel changing or reimbursing me for those wasted days and for the extra flight costs involved. I did speak to the travel agent (Pentravel Clearwater Mall), who was amazing to deal with, but unfortunately could not help me further. We were advised to lodge a formal complaint. I have documented the entire trip which includes pictures and videos of our experience. I have no idea where to send this complaint too or who to contact. I have checked the Pentravel website and there is no complaints section.
