Request for Cancellation of Unauthorized Insurance Service and Refund

I did not knowingly consent to enrollment in the EFU Family Health Insurance Gold Plan. During a call from 051-2521028, I was instructed to press 1 without being clearly informed that this would constitute authorization for an insurance purchase or result in a Rs. 1,950 deduction. I request immediate cancellation under the applicable free-look period and a full refund of Rs. 1,950. Please also provide the recorded evidence of my consent/authorization and the policy/certificate number associated with this transaction
