How can I renew my tenancy agreement if the landlord is not responding?

Hello Mr. Abdul

I'm looking for some advice on my situation with tenancy renewal.

My apartment is in JVC. My current contract (40K) is with a real estate company and it is expiring on 31 Aug'23.

I received a notification from the real estate company in May'23 about a renewal notice with a new cost (44k). I confirmed the renewal by email and they accepted it.

Later in Jun'23, I got a notice saying that the flat is sold to an individual and I have to deal with him now.

I tried contacting both the new owner and real estate company for the renewal confirmation and even after multiple follow-ups, there is no confirmation received on my renewal.

I'm worried that the new owner comes back to me asking to leave because the contract is expired on 31st Aug or he comes back and say the new rent is not 44K and it is more or something.

Please help me with what should I do in this situation and highly appreciate your advice.
