Supersaver - Reschedule of dates cost more than actual flight.

I asked to reschedule my flights i made. I Paid 142 euros total return flights from amsterdam to Zurich per person. I wanted to move my flights to a months or 2 later as we can not go away that spesific weekend anymore. Supersaver adds so many additional services fees and bull**** on top of it, it costs met 150 euros per ticket to move my fees, which is more than my original ticket only. I might as well just buy a new ticket for the same price. Absolutely redicoulous. PLEASE Dont USE them !.
