Club Mahindra Holidays — membership refund - unprofessional & cheat

Address:

New Delhi, Delhi, 110075

I took membership in month of june 2018, and applied for refund of advance paid in early aug 2018. Have called there office few times, and also sent two emails.
There people just keep calling that they will not refund any money and also there is no policy of refund even if we have not utilized the serviced of the club mahindra holidays even for 1 day.

This is absolutely cheating, mahindra has not incurred any cost to give membership, even if they want to deduct a nominal administrative fees for the same i am ok with the same.
