CheapoAir Refuse to refund our RT airline tickets to Rome Italy, which were cancelled due to COVID19 pandemic New York City New York

We booked two airline tickets to Rome Italy on 09/03/2019 for travel on 06/23/20 to 07/03/20 from Newark, NJ.  When COVID19 hit and all travel to Italy was cancelled (by the airlines) due to the pandemic, I called CheapoAir to get a refund in ealry March and they did not pick up their phones and were unreachable by chat.  They have been shuffling me around and basically I have gotten nothing back in terms of my $1471 paid.  I have complained to the DOT, BBB and TrustPilot and all that has been offered is $320 in refund and $1053 in travel certificates through Cheapo Air for another international flight to Rome only.  No domestic flight credits for reasons unknown.  We also purchased travel insurance for $95 through TripMate, which was sold to us by CheapoAir and they also do not return phone calls or emails.  This is the most dis-reputable company that I have ever dealt with in all my years of business and personal travel.  Stay far away from them
