ACSA long stay parking chaos every time

We booked AND PAID our long stay parking from 9 Jan to 12 Jan 2025. We struggled to get out. This is a very bad coordinated service. Every time we use this service you have to push the button to ask the lady on the other side to open for us. This is not as if we had to pay at the gate, we received a "bar" code to scan at the gate, but this doesn't work. ACSA get your place in order or get people who can do it for you!!
