Nestaway Technologies — rent not paid by nestaway since last six months

I have rented my flat through nestaway (Houseid: 24270).
But since march 2020 i have not received rent. I thought due to covid-19 there may be delay but i came to know that nestaway is receiving monthly rent from the tenants. Now they told me that the rent is adjusted against the security deposit. Now the security deposit also exhausted but still they are not paying the rent and instead of paying me security deposit they are retaining rent received from tenants in the name of security deposit.
Ideally nestaway should pay me sd instead they are taking sd from me.
I am trying to contact representative but nobody is picking up the phone.
It seems it is a new type of fraud.
I want pending rent till date to be credited.
