Volaris complaint: Unhappy Customers

5 of us in family, got 5 tickets at Volaris for 90th. BD, My wife left on the first week of March . 4 of us were to go the end of March, but because of the Corona Virus we at first tried to contact Volaris by the 1855.865.2747 telephone.But after 5 days of waiting between 5 and 15 minutes and automatically cut off , we tried the Volaris.com ,but again do not know why but could not change flight or get money back.
At O’Hare. Airport Volaris personal informed that we could not get our money back, but where able to change it for another day, but we had to pay around $ 65 to $75 extra for price difference .original for me was $ 248.30 with Personal item and2 Cary on. So now we pay more and we’re down gated to a personal item that must fit under the seat..My wife is in Mexicoand also had to pay extra for the return flight to Chicago. We unfortunately made reservations to go back in December before this chaos . If we knew this about Volaris we would not fly with them. The prices are the same now that they are like Spirit.
