Booked fastpark well in advance of travel. Arrived at 0500 to realise fastpark is now covid testing. Panic sets in. Thankfully a voice via intercom of a nearby carpark we stopped at to try and figure out what to do advised us to go to surface parking then explain situation on way out... Zero communication in advance to tell us Fastpark wasn't available, despite intercom voice saying Fastpark has not functioned for over 1 year... Awful service and a lot of stress. Lost 30 mins before flight due to the hassle and inconvenience imposed upon us, meaning no time to eat before 4 hour flight. Absolute disgraceful service in advance, I will be in tough to complain formally. But absolute credit to the helpful Intercom person in early hours of 16th July who was very helpful.
