Cheapticket.in / Airtickets India — refund not yet received

Hi team,

With due respect and faith, i am registering this complain to request you to kindly help me to get my refund back.
I had booked a ticket from cheapticket via ixigo on 1st december 2019, on the same date and within an hour i contacted cheapticket to cancel the ticket they explained me if i cancel the ticket on the same day only 3000 will be deducted as cancellation charge and after that it will be higher. I requested them to cancel the ticket same minute. After that, i got a mail saying cancellation charges will be 3000 inr and refundable amount will be inr 14565/- as expected as per call. I acknowledge the same within 5mins. After that i didn't repeat any mail even after multiple calls to there 24*7 customer service and mails were not responded. Later after the start of next day, they changed the refund amount to 8228 with cancellation charge as 9337 and started forcing me to accept the new mail amount.
This kind of harrassment and fraud is not expected. If they have delayed in cancel the ticket, why will customer suffer?
Moreover, 2months are over but still after multiple mails and call i am not getting any response from cheapticket. Refund is not yet credited.

Request you to kindly help to get my refund of rs14565/- from cheapticket.com.
