Holland America Line complaint: It is impossible to make a reservation for plane tickets to fly to your cruise

I booked the cruise from Jun 23 thru jul 7, 2023. When I tried to book airline tickets every time when I was ready to give my credit card number to your agent THE SURVEY WOULD CUT ME OFF! I would call again, getting a diff agent – and start all over again – the price will be diff – HIGHER?! – and then while giving my card number – would be cut off AGAIN! Started all over – got the rudest agent with very limited English, he was not answering my questions, then cut off – AGAIN! After FOUR hours of this horrible experience I got to make the reservation – with $500 difference! Because of your poor service I lost $500 of my money – ? My husband and I traveled with Holland America exclusive before – ALWAYS A Pleasure; this time the reservations for the flight was a nightmare – I hope the cruise is still good. Please look into this matter –
