Our son only attended this daycare for less than 2...

Our son only attended this daycare for less than 2 months before we switched due to some serious problems with the owner Becky and the safety of the facility.
1st problem regarding safety, my father was able to walk in without being ID'd or questioned and picked up our son without anyone saying anything. No one was at the front desk, he just waited until another parent came out. There is only one other hallway to the classrooms. Small building. Granted, he was on an approved list to pick up but no one asked his name, for his ID, or contacted us for approval. He just walked to the classroom and told the teacher who he was there for.
2nd problem was while my son was there less then 2 months. He was bitten multiple times. Now I understand children bite, my son at the time was about 18 months old. But the very first time it happened Becky and his teacher, tried to convince me that he had bitten himself so hard that when I picked him up 8 hrs later, there were still a full set of teethmarks on his arm. By the way he didnt even have a full set a teeth yet. So when it happened again, they still stuck with the same story that he bit himself the first time but 2 days later it was another kid. So ok, that makes more sense obviously. But then when Becky went on to tell me how she would 'solve' the problem, which was the isolate this little boy in a room by himself everyday. This women doesn't understand the first thing about teaching or raising children. I also witnessed her grabbing other children's arms or pushing them against walls and most definitely yelling at children. All of which is child abuse. The only time I caught her yelling at our son over wanting to play with a toy instead of sitting down to watch a TV. There is absolutely no need for a TV in a daycare. We PAY you to play and educate our children not so your teachers who are instructed to FORCE them to sit down and watch TV so they can clean up and get out as early as possible. I have worked in daycares as a teenager and never was there a TV, or If there was it was used on a very special occasion NOT to use it as an everyday babysitter. And we would have never forced a child who would rather play with a puzzle to watch a TV show everyday so we could clean. Cleaning was and should be done after children leave the room. I'm not taking about picking up toys, I'm talking about using chemicals to clean off surfaces and floors.
3rd problem which made us remove our son was again regarding Becky and safety. After our son was diagnosed with some food allergies to dairy and cows milk, we informed Becky and his teachers. She had us complete some paperwork and get a dr note as well as an epi pen for the daycare, which is completely understandable. But then we found out they were still feeding him cheese because they notated it on his daily sheet. I informed Becky and she then instead of apologizing and trying to make sure it didnt happen again (which it did), she tried to argue with me that cheese was different then cows milk and his dr note didnt list cheese or dairy just cows milk. We then proceed to have a ridiculous conversation about cheese, dairy and cows milk. I then had her pull out the dr note when she realized it did state both cows milk and dairy, she still never apologized for feeding my child something he has an allergy too. Had she done that with peanut butter he is allergic to as well, who knows what would have happened.
She then went on to inform me that she wasn't RESPONSIBLE for what happened in the rooms when she wasn't there. She also called us to a meeting were only my husband could attend due to my work schedule and she had her husband come to basically try to intimidate us, which didn't work. My husband told him to leave the room since he wasn't an owner, teacher or had anything to do with the daycare.
This women is dangerous and has no fear or remorse for her actions. She doesn't care about these children she just wants the money. She needs to have her license revoked and at the very least investigated.
