Urban Company — tiffin service

Address:

New Delhi, Delhi, 110019

I got in touch with a tiffin service provider in Govindpuri through urbanclap. His name is Abhay. I subscribed to his service and paid one month's expenses, all in advamce.
His service was fine uptil a certain point. The holi vacations were coming up and he said that he would continue service post that, which he didn't. On calling, he said he'll not be able to provide service due to financial imbalance in his business, but will refund me the money for the remaining tiffins.

Now the thing is that he is unable to do so.
I don't have his address, his calling number(that he changed), I only have his whatsapp number to which he doesn't respond anymore.
I have asked him to get even by providing me with the service at least, to which he doesn't respond either.

I want to way to get to him now. What do I do?
