Make My Trip - Refund for visa due to mmt mistake

I booked hotel Novotel at Zurich airport Messe from mmt from **th to **th Feb and applied for visa depending on the hotel booking voucher that mmt provided. My visa got rejected as when the embassy contacted the Novotel hotel in Zurich the hotel informed there is no such booking done through mmt. I had already paid ***** rs for visa and all my other booking like flight had also cost me a lot of money. Now due to this confusion, I had to submit my visa again which will again cost me *****rs. I had to pay ***** extra for visa again and also the visa rejection procedure was a headache for me.
I contacted mmt for the refund as I had to pay extra because of mmt mistake. Their representative did not concern to call me and provide an update. Later they confirmed to pay my visa amount in my Hdfc bank account and took my bank details in an email and on call. I have those call recording and emails as well. Later mmt directly gave the refund in my credit card which I booked the hotel from which I never asked. mmt has kept torturing me regarding the refund and forced me to take the refund in mmt wallet which I refused. They first confirmed that they will refund amount in HDFC bank then without my approval they gave less money in my credit card which I never asked as I had paid cash for the visa.
