MakeMyTrip India — no refund for visa cancellation

Address:

641006

MakeMyTrip have started new visa service last year, I was planning to go to singapore and send them passport details and money for visa for me and my kids. Next day they called and said tickets are compulsory for Singapore visa since my travelling dates were not clear due to coaching classes I couldn’t book tickets so I cancelled visa application, I paid for 3 visa application, they say they’ll refund it in 15 days but not refunded till now as of I check my statement if the refund is to my credit card, I also want confirmation from them, there is not specific costumer care department for visa section and tickets and other section people say they can’t help me with this. So I am trying to contact MMT for past 7 months about this visa cancellation refund but no help, I even sent mail to their customer care but no response
