Nobroker — Damage to the property

I had booked bathroom cleaning with
No broker. Partner who had cleaned the bathroom have damaged the floor. Such a hard chemical/acid was used that my white floor has turned dark brown. I have been complaining for over 2 weeks but no action has been taken so far. On 3 instances i was being promised that the cleaner will come and will resolve the issue but no one came. No broker agent was in conference when the partner refused to come and clean and was shouting on the top of his voice. He had also cross checked pre and post cleaning pictures. In the picture you can also see that the colour of the pipe of hand shower has also changed. I had spoken to their supervisor and Citi manager but nothing has happened yet. I was being promised that by 19th sep this issue would be resolved bur again no one turned toll now. Such a pathetic service. Citi manager ks Mr Shahid/ Shabid, customer care agent is Kinshukh, manager was Miss Manveen I believe. Can this be taken care of? Cleaner was Janender
