Consumer Redressal

I have booked a ticket for my family to travel to India on April 3rd and return flight on May 4th. However due to covid 19 situation flight got cancelled and I got a flight cancellation e-mail and PNR number is F69VQY Then I have send an e-mail to cancel my full ticket and issue a refund for the same. Then I got a reply from your customer service stating that they have cancelled the ticket issued a full refund which will be refunded back to my credit card with 10-15 days. I haven't received a refund even after 15 days. Then I have contact your customer service over phone and they told me that refund not yet processed and he will send a request to process the refund back to my credit card. Since I haven't received a refund confirmation. I have again send an e-mail to your customer service and Mr. Raj replied back without checking any history of my mails stating that he have issued a CREDIT SHELD, which I don't want. Since based on current situation I don't have plan to send my family back to India I have all the e-mail communication, including refund confirmation email stating that the refund will be issued back my credit card. Now I’m paying interest on my credit card every month for this amount and contact so many time Spicjet via email, which no replying and even calls no one answering. It occurred on: 22/03/2020 Initially they were replying for e-mails and calls but now no reply for email and calls. Still not received my refund and i'm paying interest every month now for this amount on my credit card
