Worst customer service

Worst customer service. They do not care about their customers and are not willing to help in any way. I had already checked in online and when I came to drop my bag off, I was told it was too late (flight had not even started boarding yet) and I had to drop it off 40min before. When I went to ask for help and if my bag could possibly be put on another flight (willing to pay extra), they were rude, uninterested in helping and did not seem to care one bit. The money for the flight was lost and I was told I had to pay for a new one. Not impressed at all!
