Waited in line for three hours

Everything was satisfactory except I didn't get the model I booked.

Picked up the car at the AVIS counter in Munich Central Station. There were two cars to choose from, both upgrades from what I reserved. I chose a high-end automatic diesel S-MAX with navigation. The staff was friendly and provided detailed vehicle information. They also gave me a parking card and a map of the garage. When returning the car on a weekend, the store was closed, so I parked it in a street spot near the entrance and put the keys in the drop box. The staff called me the next day to confirm they had received the car. The whole process went smoothly. One star is missing because I couldn't upgrade to a BMW or BENZ in Germany, which was disappointing.

The customer service agent at pick up was extremely rude. I called the service hotline 2 hours prior to arrival to say that our flight was going to be delayed, I was reassured that the my message will be passed on and budget staff would track the flights and stay up to 2 hours after the opening times if needed . We arrived at the counter 2 minutes after they officially closed, luckily bumping into the lady on her way out. She told us that the counter is now closed, no one told her about flight delays (although I added the flight number to the booking) and she can not re-open for us and that it was not her problem. Only after 10 minutes of persuasion she agreed to open the desk again - which took her less than a minute. When dropping the car off they tried to charge me an additional €80 without explaining why (I had payed the booking already). I refused to pay and it turned out that budget tried to charge me for a deposit for fuel although I returned the car with a full tank. Overall a disappointing experience - I will not book with budget again.

I would be more interested din Budget to rent a car if they put unlimited millage instead of 400 KM.

I think the offers are good but it can be improved if you can suggest better deals.
