New car purchase (day registration) Equipment missing

Hello, I am new here and hope that I have landed in the right subforum. I have the following problem or question: This week I bought an Ateca FR from the Seat dealer as a daily registration. Both in the advertisement (for mobile and autoscout) as well as on the exposé, which the seller sent me was listed with the special equipment the top view (360 degrees) camera. I then assumed that this is also installed. After we went through the documents and I the Vertr ag etc. had signed, I noticed that in the equipment list in the contract the said camera was missing. I then said that I wanted to look at the car again and realized that it is actually missing and only a normal return camera is installed. Since it did not inform me before that the equipment was missing and this was listed in advertisement and exposé, I wonder how I should behave now. After I told her that it was missing, sa I asked to offer me something else instead (e.g. services). According to the list price in the configurator, the TopView costs 570 Euro. After consultation with the management, I was offered a full tank filling (value about 70-75 Euro), which seems to me plentiful little. Is this now culanz from their side or do I have more possibilities and rights , some ra Thank you very much!
