Miami Rent A Car

This was a bad experience, very unprofessional. We got there and they didn’t have our reserved car. Okay, it sucks, but that happens at rental car places sometimes. Whatever. They gave us a temporary car to drive around while we waited for our real car to get in. An hour later they call us urgently three times telling us the real car is there. We go back and after an hour of waiting, the real car still is not in. They said they were out of child seats until we insisted we had to have one. Then they magically found it. One of the employees lied to a customer on the phone about how long it would take to pick him up, then told us this was a lie as if to let us in on the ruse.
When returning the car (at the pre-​arranged time of sunday 6pm), I got several messages from them explaining that they close at 5 on sunday and even though I have a 6pm appointment, could I come back early so they can go home? I couldn’t, and would not have even if I could. I arrived at about 6:05, and in those five minutes after six I got another two messages from them, urgently explaining that the car really must be returned on time. After they kept me waiting two hours to get it. They also overcharged me for the child seat.
Bottom line– I rented a car here because it was cheaper. Absolutely not worth it. Stay away.
