Disgusting customer service & no regard for client

Our flight was at 6:15am on the 27/02/2016. We got to the airport just in time to do use one of those electronic check ins but it wasn't working, then we ran to the desk and they say sorry flight closed , the supervisor had a terrible attitude and refused to help us even though we were 5mins late , boarding didn't even start at that time but she point blank refused and was extremely rude. I have never received such pathetic service from an airline before. They have no regard for their customers and their response is they can't help or do anything. I am livid with the service I received this morning from Flysafair. I was shoved around from place to place trying to get assistance but no one could do anything. This level of service is unacceptable. I didn't even have luggage to check in, I have seen other airlines making a plan for passengers before but Flysafair doesn't even have staff that can speak proper English or have the capability to solve a problem or assist a customer. This is a Mickey Mouse airline and should close down! Really so disappointed and angry !!!
