Advertising without consent

I live in Fleurhof extension 3, Flash people came to my house and painted my walls without my permission, They painted my walls without my consent and I do not understand why my property is being used for advertising without my consent, I expect compensation for the advertising, or else please come and remove your paint and your adverts. I do not understand why they would even do this without speaking to the owner of the property, IMG_***.jpeg
