Company refusing full refund of cancelled flights

spencer59

Hi, 
I am due to fly to Australia via Hong Kong on 20th July, with Cathay Pacific. I have been informed by Get a Flight, who I booked with, that all of the flights there and back have been cancelled. I have asked for a full refund but been told I can only have the money back minus the taxes which amount to over £300. When I've queried this, they gave the response I've copied below this post. 

Can anyone advise me please whether I am entitled to a full refund and Get a Flight are just trying to hold on to some funds, which I understand in these difficult times, but nonetheless, this does not help me. Or are Get a Flight correct and I am not entitled to the full amount back? 

I always thought that a full refund was my legal right but if I'm wrong, I will have learnt something. 

All advice, much appreciated, thank you.

This ticket has been booked in special (Discounted
fare) of the airline within that
whenever we normally cancel the tickets we get
only taxes back from the airline as
tickets come completely non-refundable category
however these tickets are canceled
from the airline due to Covid-19 we will get the
maximum amount not be able to get
back those taxes ( Airport, UN, YQ, YR) from the
airline and supplier who issued
these tickets.
