Unpleasant stay and experience

We booked a 8 sleeper at Stonehill River Lodge in January 2019 for 20 - 23 September 2019. We were contacted by the staff at the resort closer to our stay to enquire how many people we would be etc and we enquired if it's okay we more than the 8 required and will pay the extra amount of which they then said we are only allowed 1 person over. We also arranged for the key to be left under the unit mat and they confirmed. We told them that we can't understand as 2 years ago we booked a 6 sleeper and we were 12 people and now we booked a 8 sleeper we are 11 and not allowed. My sister and myself were contacted by Natasha at the resort and it just went down hill from there, she was unpleasant and her attitude didn't help at all, we were also told that the key would not be left under the mat anymore abd that we must collect it from at reception. Ben the guy at reception was not friendly at all during our stay and to top it all they wanted to charge us for visitors we didn't have,Natasha informed me that the little boy informed the office that we will be receiving visitors, her story then changed when she told my sister that the wood guy informed the office we ordered more wood cause we will be getting visitors. We felt like ********* and this whole experience wa just unpleasant.
