Auto House - Added in many charges without advising that they were added in plus did not offer or give signed paperwork Phoenix AZ

My daughter who is 23 was so excited to buy her first car and purchased her first vehicle here at Auto House.  I was with her up until the time of signing the paperwork,because I needed to be somewhere and had to leave.

 They advertised a 2024 Prius  for $27,500 with only 1000 miles on it.  This was a little higher than my daughter's budget so we tried to negotiate to $26,500 and after a couple back and forths, it was refused, so we got up to leave, and the manager then came out and eventually he agreed to $26,500.  His sales pitch was this was like a brand new car with only 1000 miles but getting it as used.  
I felt comfortable leaving my daughter to sign paperwork because my son and I both purchased vehicles from them, when they were previously called "the Collection of Scottsdale."  In hindsight a very different company now.

My daughter got home hours later and my first question to her was, "did they try and sell you a service contract?"  Her answer was no, and that they didn't explain or go over anything with her, but only told her where to sign.  She mentioned being exhausted from being there so long, and I alone had been there with her for about 3 hours before I had to leave.

She did not receive any copies of the paperwork she signed.  And it took several phone calls and finally after 3 1/2 weeks she got the paperwork emailed to her.

The vehicle was financed and she put $9000 down.  It was quite a surprise to see that she was financing roughly $29,000 because they added in the normal taxes and registration, but also added a service contract that was never mentioned for $3995, gap insurance $1200, $1495 theft benefit, $599 ceramic tint , and $1199 of unexplained money.  None of these were explained or even mentioned, as she was only told where to sign.  Nor was she advised to read the contract.  She had no reason to expect anything more than taxes and registration to be added in.  

She was overcharged $8488.00, however with a penalty, she was able to get back the money for the service contract and the Gap insurance.  Still being overcharged $3583.00, and later being advised that the theft benefit and window tint were non refundable.  No explanation for $1199 being added into the price.

This company appears to hope the customer won't ask any questions, so they can sneak in all these extra fees.  Therefore once the customer signs the paperwork, then they stand behind the contract being signed, and stating the customer knew exactly what they were signing.  

This is so wrong, because they completely mislead the customer on any aspect they can!  Contracts should be understood before they are signed and an honest company will not hide behind the contract,with ill intentions, while it is being signed, as this company does!
