Nestaway Technologies — deposit refund not provided and removed access from dashboard also not even answering to calls and mails

I have moved out of property on june 13th 2020. The area manager is supposed to collect the keys but he didn't arrive and i have handed over keys to security and informed the same to him with contact details and they were still not collected. All of sudden access to my dashboard is removed now i am not even able to raise a concern to get support. I kept on calling the team everyday numerous times no one is responding to calls and many mails and follow ups no reply on that as well. I feel they are not interested in sending the money to tenant as per policy. This is against to their terms and conditions. Being a consumer based company they should be responsible to their consumers discomfort caused.
