Unclear about what's included in the price, priced incorrectly

I arrived in Munich at 5:30 AM and followed the signs to the car rental company. However, I learned they don't open until 6 AM. After they opened, I was ready to pick up the car, but the staff apologized and said they couldn't find the keys at the moment, so I had to wait. I had reserved an automatic car, but the rental staff asked if I could drive a manual and upgraded me to a BMW 116i. Since I had a meeting at 9 AM, I opted for the manual. Overall, the car was in great condition and it was very good.

1. Booked an automatic Golf on Zuzuche, total price was around 5600. At pick-up, they said only BMWs were available with automatic transmission, costing over 10000. 2. Rented car for a month but it had no spare tire and they didn't inform us. Resulted in a blowout en route to Rome costing much more. Towing fee was 150 euros, plus 480 euros for two new tires, which is unacceptable. 3. The actual rental company was small, and after the blowout incident, we called but no one answered and there was no roadside assistance. 4. The rented car had many small dents. During return, the inspector falsely claimed that pre-existing dents were caused by us. At pick-up, they acknowledged these were pre-existing but did not recognize it during return inspection. This left a bad impression.

The female staff member at Global Drive who assisted me was very unprofessional. I repeatedly asked her about full insurance, but her explanations were very vague. This ultimately cost me almost 400 euros extra.

Did not have available the car I booked. Why not? It was fully paid in advance with a fixed arrival time. One hour into my journey the car developed an engine running fault. It took 5 hours to source a replacement car through an alternative hire company with an additional EUR580 cost.
