Cleartrip - Refund for Cancellation Travel Restricted to JP

I booked a ticket for Travel to Tokyo from New York via Cleartrip in November ****; the trip Id is ************. However, on November **, ****, due to the spread of Omicron, the Japanese Consulate's Website indicated that " As a strengthening of border measures for the Omicron variant, foreign nationals will be suspended from entering Japan for the time being from November **, ****, for the time being (Including those who have an existing visa)."
Based on the restricted entry for Non-Japanese Nationals, I requested cancellation or a future issuance of travel credits on December **th, ****. Since the past three months, I have sent multiple emails and called customer service at Cleartrip, requesting either a full refund or a date change for future travel on the same route; however, there has been no refund or credit for future travel received to date.

I called Lufthansa at their US Number +*.***.***.****. I was informed that the ticket is “unused.” Since the travel period was within the time frame when the foreign nationals were restricted from entering Japan due to Omicron, the ticket is eligible for a refund or date change for the future. However, since this ticket was purchased via a travel agency, the Airline cannot directly process this request, and it has to be channeled via the travel agency.

It has been almost three months since we have tried to resolve this issue to no avail.
