Took multiple days to pick up a car at MCO, and not the type of car I had pre-paid for

After queuing for over 2 hours at MCO airport waiting to collect a car, whilst my 3 children and 2 elderly relatives waited, I decided to cut my losses and get a taxi to our holiday rental - we got into the property after 10pm having landed at MCO before 6pm. I then had to return to MCO the following day (another taxi fare incurred) to pick up the rental car I'd pre-paid for. Now I was told that no large 7 seat SUVs were available and they managed to find a small 7 seat SUV, though still at the same price. This experience has put me off using Budget again.
