Thousand Trails review: cleaning charge

We stayed at this cottage Aug3-10 and upon arrival our cottage had no hot water, stove didn't work and the fridge wasn't working. We patiently waited while our freezer items defrosted in our cooler. Finally at 9:00 that night the hot water was back working. We were offered $50 off our stay but still have not seen that discount on our bill. The fridge started to work the next day. The rest of the stay was ok. Pool was closed several times but overall not a bad stay. The cottage itself was fairly clean but there was some garbage in pull out couch. When we left we cleaned our mess, took out garbage, swept wiped down stove, counters etc. When we arrived home there was a charge of $108 on our visa. I called and the manager quickly passed me on to what I guess was the maintenance guy. He would hardly let me speak and went on to say the charge was for a bag of muffins I forgot in the freezer and a mascara container that fell behind the toilet. I was very upset! He then said my teenage daughter left tampon wrappers on the floor! Now I'm fuming because how dare he say she did that. First of all she is young and not on her period nor was I the entire trip! So a totally lie! He mentioned her several times and it was very upsetting! I did tell the office at check out I had two mugs soaking because we ran out of dish soap and didn't want them put away dirty. When I asked about the $50 refund he said we shouldn't get it anymore because he had to come on his time off to fix the cottage hot water etc. WTH not my fault or problem. I have friends who have been going here for over 8 years and said this place is not like it used to be with new management. I'm so disappointed in the charge that was not even discussed with us. He would not listen and was very unprofessional. $108 for those little things is so disheartening. Is there anything that can be done? Please contact me.
