Nestaway Technologies — Refund policy violation

I moved into a nestaway property of noida goes by the address c-157 sector 72. We submitted a one month security deposit also. On 1st july 2020 we moved out of the rented property and were assured the refund within 7 days but there is not a single call back or mail received regarding the same. I have tried reaching their numbers but no response. Its not only me but also thousands of other as well who are facing the same issue.
