Nestaway Technologies — Nestaway security Deposit refund House Id - 52951

I am stuck in a tenancy issue with nestaway as they are not returning the fixed deposit with a reason that Owner hasn't initiated a refund.

We kept paying as regularly. Due to covid we needed to leave the house and we gave a month notice period vacated the house. Nestaway manager visited and gave a clearance and collected the key.

But now the security Deposit is stuck with them . It has been more than 4 months now. Want to give a legal notice to them. I have kept record of all the invoices and payment have been online. Every track record copy is available.
