Sunstar Club — Refund

Website:

sunstarclub.in

I got a call from sunstar representatives to meet on a dinner in welcome hotel, dwarka and we went there on 17th dec'16. We were offered a membership of 20 years, which i deny and said cant afford this.
Representative (Pawan) asked me the price/tenure i can afford and he offered me 5yrs. Membership for 50, 000/- which can be paid to bank in 24 equal installments as sun star have tie-up with standard chartered bank.
I paid the amount by credit card of 50000/- and didnot receive any call from bank till 20th dec'16 regarding emi's, then i approach bank and they deny to make the installments, after this i approach the sunstar representative mr. Pawan and told me that he will get the excess amount of interest of rs.48000 of emi's to me, which was not easy to digest.

I keep on taking to this guy and sometimes he talks and sometimes didnt pick the call and like this 3-4 days passes away, then i wrote an email for refund on 25th dec'16, they didnt answer any email.
I was giving daily follow-up on email but didnt received any revert.

Then i came to welcome hotel on 29th dec'16 and met tapas (Agm) and mr. Sudhir (Agm), mr. Tapas informed me that he will initiate the refund on 31st dec'16 and will keep me in loop.

Today is 3rd jan'16 and nothing has happened till now. No one from them is picking the calls, and neither responding emails.

I do not know, how to tackle with these guys as everyone is making false promises and thereafter stop picking the calls.

Someone please help me, how i can get my money refund.
