Fargo Travel Agency review: Ticket cancelation

On 5/8/23 we purchased 2 direct flight first class Delta One tickets through Fargo Travels("FT"), who disclosed as acting as an agent for Delta Airlines. We did receive a confirmation from Delta that we had tickets at that time. On 9/19/23, within 2 weeks of our departure, we noticed our tickets no longer showed on our Delta app. Contacted Delta and their representative stated our tickets were canceled on 8/24/23 due to an "improper fair and a possible fraudulent transaction" completed by FT (no further information). The Delta rep expressed that communication regarding this issue was between Delta and FT and the responsibility of our canceled tickets was on FT. We were never alerted by Delta or FT of this issue. Delta could/would not reissue our tickets on that flight causing us to repurchase inferior one-stop tickets at a premium of over $5000 to get us to and from our destination to accommodate our prepaid 2 week trip abroad. We contacted FT on 9/19/23 and could not get a direct answer as to what had occurred, however, FT did refund our ticket costs. At this point we continued to pursue answers from Delta while they continued to point the blame to FT. I have now made 3 attempts in writing in addition to phone call conversations with the FT reps (Keith/Blake/Adam) who have been involved in our transaction since 9/19/23, asking them for specific communication records between them and Delta to better understand who is responsible. At min, we believe Fargo Travels is accountable to us for specific answers as to how the transaction with Delta occurred, and confirmation of the transaction as being legal/accurate/acceptable and any/all communication with Delta from 5/8/23 to 8/24/23 (day we were told Delta terminated tickets) and to today. We have received nothing but radio silence. We believe we are due compensation for the tickets price differential as well as a value for inferior tickets we had no choice but to purchase.
