Poor service, lack of proper directions for after hours service

I booked tickets with flysafair to attend a funeral, I booked the ticket at 19.22, the flysafair site didn't tell me anything about it being a last minute booking or a remaining seats booking or that there's 12 minutes left for boarding, if there's 12 minutes left for boarding, their site should advise customers that there's 12 minutes left for boarding before we book the tickets, at 19.26 I tried calling their call center to either cancel the tickets or change the time for a later time cause I couldn't make it to board in 12 minutes, the call center says they open from 7am to 7pm, they could advise that for issues like that we must go to the airport or provide some way of assisting us with this issue, their email is responded to by a bot, there's no human interaction for us to change this, then there's the horror of dealing with their staff at the airport who advised us that she made notes of our situation, but she **** cause she put notes that there's nothing to be done about our situation, I called the call center today and spoke to Viva and the her supervisor Rudy, who told me I booked the tickets so why didn't I see before I booked the tickets that there was 12 minutes to board, when I told her that it only showed us after booking the tickets that there was 12 minutes to board she said that was not the case, but it was the case and I have my call records to prove that 4 minutes after booking we tried making contact, we were in a crazy situation and I find it appalling that nothing can be done to assist us in finding a solution that works for all parties concerned. Flysafair staff lack empathy and are extremely rude... I told the manager Rudy that I am not asking for a full refund, all I'm asking for is for them to look into the issue and find a solution that works for everybody but I was shut down at every corner on this issue
