Club Mahindra Holidays — no refund even after 2.5 months

I was assured of membership cancellation and complete refund on 7th april and got written mail also from member relation team on my registered email (From shreemathi) with cancellation request no also mentioned - 075174 (Membership id generated was 2811651 which member relation team is not able to find in their systems now) but after that i am constantly following but no body has clue on when refund will be processed. Don't expect such behaviour from reputed companies like club mahindra which is not able to honour timelines of written commitment given. Can somebody confirm me exact date of refund as on mail there is absurd response and on call back team says will check and call back where call never comes back.
