Radical 9 Apartments Baner Pune

I have vacated the property Radical 9 Apartments in Baner Pune in the month of nov 2020. It’s been more than 4 months and I have no way to contact them. I tried speaking to customer care and they denied any help on this. They asked me to create a service request and the request was closed without any intimation on action being taken. Please assist
