Cleartrip — cannot amend cleartrip flexifly ticket to another airline on same day

My mom was stranded due to covid lockdowns for more than 2 months and hence i was desperately looking for booking a ticket with amending option because applying tn epass required us to book the ticket upfront. After several searches, i booked spicejet 20:25 delhi to chennai ticket on cleartrip website with flexifly (Digit insurance) so that i can amend the ticket if required. Finally when a need came the website would not let me amend, asks to contact +[protected] which says temporarily blocked. No email to contact. Their support is auto chatbot which loops and finally was able to submit a feedback where i typed in the issue and requested to change the flight to different airline on same day. There was no terms and conditions said that the change is possible only within same airline. Digit insurance also confirmed that we change the ticket to different airline but cleartrip continuosly denies and cheated me. Since i also suggested other passengers totally three o[censored]s were cheated. Thats when i wanted to bring it to public so that others can at least be made aware of. Please dont buy cleartrip ticket because of flexify option. It doesnt work at the hour of need.
