JustFly FlightHub Refuse to issue refund WA

I have requested a refund as is mandated by the DoT for flights cancelled due to CoVid, Flight from GGT-FLL, 04/16/2020, returning FLL-GGT 04/20/2020. I spoke with Silver Airways directly and they confirmed that I am due a refund if requested vs. a travel credit but that the online agency I used would issue the refund.  

I spoke to a representative this morning (04/16/2020) live on the telephone at JustFly who confirmed that I would be able to get a refund vs. a travel credit but that I needed to send an email to customercare@justfly.com.  I have done that this morning and they are advising that the airline is not issuing refunds and that they will only provide me with a travel credit.  This is wholly unacceptable as I am entitled to a refund.  They must think I am unaware of my rights.
