Can cooling period mention in agreement can be overirde

I took membership of country club and in their term and condition there is cooling period clause. I have cancel membership and asking for refund.I have send email to them on 4th days from date of first payment to cancel membership and refund my amount as per clause specified in their agreement . Is my claim valid ?Can they still bypass and not refund the amount. I have file FIR and going to file case in consumer court. Please provide your suggestion/advise. Cooling period from agreement is as below: ================================ This is a "fee for service" membership and is not a deposit and niether an investment. However should the member desire,refund can be sought within 7 days from the date of the first payment by emailing to [deleted] refund will be processed and an amount at the discretion of our management will be returned to the member with a reasonable period,after deducting an administration fee of RM1000.After this 7-day period,there shall be norefund for any reasons whatsoever.
