Cognate Health Services — Complaint against health plan

Address:

9&10 Must No-2 Kila No-17 Second Floor Vipin Garden Extension, Main Najafgarh Rd, New Delhi, Delhi 110059

I have purchased the plan in february 2020 for the validity of one year.
They have given me the voucher for dental treatment for the validity of 6 months.
Two voucher for full body check up with the validity of 6 months each
And the medical facility from the impaneled partners but at the beginning they said one can avail the services from any where we will give reimbursement.
But now it is all in vain.
I want my refund because they are not giving any services.
