Easy rental process - exceptionally disappointing upsell from counter staff

Friendly and patient. Explained things professionally and clearly.

It was very fast check in but to drop off, it was Christmas Day and only 1 person worked. We had to wait more than 20min outside to return the car

Arrived in early morning and meet staff at Thriffy counter. Vehicle was not available at time to pick up, need to wait few hours , and no shuttle service. Finally, staff arranged temperory car and advised that should fit is till afternoon, but it was too small to fit my family and baggages. 8n afternoon, no courtesy call talk to inform us for picking up. Bad experiences. Pick up at late afternoon, but it was not a highlander that not match my initial booking .

The car computer kept displaying maintenance needed for tyres and maintenance needed for oil and filter. I rang the staff and they reassured me that this was not a problem but as a user it was disconcerting to have this flashing on the dashboard through my whole journey.

I arrived at the ZQN Thrifty counter as advised and our flight was delayed by 7 hours. I had called and advised the counter staff of this prior. When I arrived, a family were dropping off their key and three staff were on the counter. One was talking to the customer about their holiday and 2 were completing invoices of some description from the EFT-POS receipts of the day. Neither acknowledged my presence or stopped their task to assist me and my booking for a good 5-10 minutes. Then just as it was wrapping up, a person waiting behind me pushed in and the lady who was talking to the other customer took him first. She could see I was visibly upset by and did attempt a silent apology, but I was furious as I had already been waiting patiently and someone who barges in was given priority. In addition when I was receiving my car paperwork, I was advised we had been upgraded from a compact car to an SUV - I was happy with the car we ended up with, but shocked to learn of my booking being classed as a 'compact' as even on this website page it states 'intermediate' So I was shocked to learn we could have ended up with a compact car which is not what we ordered.
