Kerbside Disaster staff blame IT system

On Sunday 24 Jan 2021 we ordered food online for pick up from Nando's Malibongwe Drive Kerbside Parking bay scheduled for 17h15. Received confirmation of order 7464/650908. However when we arrived and parked at the specified parking bay, no one came to assist. We waited 30 minutes then drove to staff member at drive thru who sent us back to parking bay. A staff member came to chat and informed us they did not have our order. Then another senior staff member came to tell us same thing but said she would call the call centre . A third staff member came to chat and asked us to wait 10 minutes as they prepared the order. He blamed the Call center staff member and then blamed IT system for not passing on order to them. There were other cars that arrived and waited for their order, received no food and decided to leave without been served. This is unacceptable service and for price I paid for our food R319, I would expect better service delivery. Please follow up
