Incompitent service

I have no word for what an employee rush to knock off did to us....... I was late to. Check in my luggage by 7 minutes before the check-in closes 45 minutes before the flight. However the lady who looked not intrested to help at all turned us back saying the check in was only for the fact that she was rushing to knock off.... The is a grace time of 10 minutes and that wasn't allocated to me. She straight away pointed us to ticket counter where they made me buy another ticket without refunding a cent..... Totally **** and I paid my hard earned money because of an incompitent employee..... Saw her leaving just after all giggling and laughing with her boyfriend... Sad
