Spice Jet Airlines — Spicejet agree to provide refund amount due to medical emergency and now they are not providing the mentioned amount

Due to medical emergency I cancelled and submitted the medical documents and proof. They told me the amount of ₹3242 as a e voucher . I asked for the money credit in my account but they denied it without considering the medical situation. Which is not even fair. And now they are not giving the e voucher mentioned by their own company in previous mail now they are again reducing money unwanted, already they deducted the cancellation fee of ₹800 now again deducting and mentioning the wrong amount. Please help me to get my money mentioned by the spicejet. It would be really helpful.

Thank you.
