[Resolved]  Cars24 Services — Cars24 not refunding service charge

I had select a honda amaze on cars24 website and after that i got a call from their relationship manager (Yogesh). We done a deal after checking car in front of seller and relationship manager. At that time i paid 10k to seller as token amount and rs 8260 as service charge of cars24. But after 4-5 days the seller refused to sale the car and the deal collapsed. I informed relationship manager (Yogesh), he told me that he will arrange a refund of token money and service charge. But its been around a month and still i am waiting for my service charge to be refund. The seller and i talked personally and the seller agreed to pay my amount. But i have written 2-3 mails to cars24 and i also contacted relationship manager but there is no resolution of my matter and no refund yet.

Also there is no response from cars24 yet.
They are such a liars also very unproffessionals.
I urge please help me in this matter and provide any solution.
