Housejoy.in — house full of fungus after deep clean services (no fungus was there before cleaning)

People who did the deep clean services used wet clothes to clean the walls and furniture. Inspite of requesting them to do dry vacuum and plain brush, the said this was better. I spent 7000 and now ended up having fungus on walls and furniture.. Any number of mails and calls, customer care says we are looking into it. No one even came to check what happened and why.. I have a one month old child at home and they are not realizing how harmful this fungus can be on the health..
One of the calls they said deep clean services are good for once in 6 months and later they said we give guarantee only for 24 hours.. If i have to get deep cleaning every 24 hours to keep my house clean then i need pay 7k everyday!! I need someone to address this asap..
