Nobroker — awaiting refund amount of money back plan

I registered my property for rent on no broker on 27th july and i received minimum 5 calls in a day asking to go for paid plans and it gives quick results in finding a tenant etc. Finally i paid 7000/- and took no broker money back plan on 31st july. From that moment onwards i didnt receive a single call from your team. I had to chase and ask for the progress. First sandeep was assigned as relationship manager and then it was changed to deepak. After no succesful leads from no broker, i finally managed to find a tenant myself on 24th august via some other agents who i had to pay additionally. I found this tenant on the same rent amount as communicated to no broker. I have shared the rental agreement copy with deepak on 27th aug. I havent received my refund till date. Please help here.
