Urban Company — Damage of personal property while availing ghe the chimney cleaning services

I had availed the chimney cleaning service today . I have used UC for the first time and experience was very disappointing. The person came late by 50 mins, further he damage the kitchen platform, the black colour of the kitchen platform is faded because of the chemicals he used to clean the chimney . He didn't use any paper or cloth to protect/cover the area. Now the kitchen platform and the area near washbasin looks very bad . I had complained via UC app and no body bothered to reach out to me . Very poor services, biggest mistake made by availing services from UC
