Disappointed with the services at travelstart

I booked a ticket 08 Feb 2020 to travel 26 Mar 2020, we had a lock-down on the same day that i was supposed to travel. I did not receive any emails from Travel Start to say that they are aware that i will not be able to fly on the day and that they will credit my account which would have made life easy. I have tried numerous times to reach out to travel start regarding this but till today i don't have a credit in my account instead my ticket shows as used (Past). This has taken so long because i only get automated responses from you and no actual human dealing with my query. I need to reuse the funds please credit my account.
