Airlink don't care if you're not there!!

Booked return flights to Port Elizabeth. Arrived ahead of time at OR Tambo. Upon check in, had some admin issues. Was delayed by an hour. Still had time to grab a quick breakfast. Boarding gate gave us 15 minutes to board. We arrived late. I know it us mostly our own fault - we need to make sure to be on time. YET, Airlink made NO effort to get hold of one of us four passengers to make sure we are at the airport and ready to board. Just a quick phone call and we would have been there. Upon return from PE airport, sitting at the gates, I watched another airline go out of their way to find the last passengers not boarded yet. I won't use Airlink again!!
