Depature Time missed with 1minute 58 seconds

On Sunday,the 25th of Oct we had a flight booked from OR to CT.We stood in the check in point when a friendly gentleman said we can go stand in front of him seeing that we needed to check in and the queue was long.When we got to the counter we were assisted by the MOST rudest person with the worst attitude,but this is common thing with FlySaFair.She informed us that we missed the check in time with 2 minutes and we can go to the counter and book another flight.When we asked if she was serious she then saw us standing in the queue to check in on time she just said go to the counter.She seemed to love the attention as she raised her voice numerous times.We went to the counter to ask if they can assist, they just sat and said we need to book another flight.I contacted FlySaFair this morning to talk to someone regarding the matter and I was told they do not have a complaint/customer service department and I need to use social media for any complaints. Is this the reason the air fairs are so cheap, so FlySaFair can employee rude staff and make you buy new tickets for being 2min over the check in time when the staff takes there time to assist at the counters? FlySaFair responds please?
