Colive — Refund not processed even after email commitment

We were new to Chennai, and essentially looking for apartments to stay. A Sales agent with the name Rinku, approached us, and essentially asked us for the details and said that we needed to pay 1500 INR to check out the property. Usually Colive does not provide refunds. But, this sales agent committed over email that they are going to process the refund. Initially, he spoke on behalf of Colive. But, then they mentioned that since it's an associated property, we will get the refund. Upon constant pestering, he provided us with the Google map location of the accommodation where the property manager said that there were no place to stay. Essentially, the accommodation looked very different from what it was shown on the paper. After the sales agent pestered us till the middle of the night to make the booking amount of the other two rooms as well. When we declined, he started hurling abuses like "liars" at us. Then, he threatened that unless we pay the whole amount, he won't process our refund. This mockery of the stay situation continued where we told him that we were done with him and his behavior and that we wanted our refund, to which he said he is looking into it, and now, saying that he is not even going to process it.
