Injury to pet

Royal paws used to come and clean all 6 of my dogs ! They cut my spaniel once and we forgave them as a mishap! We went away in December they Cut my spaniel AGAIN who then needed stitches and a drainage! Royal Paws refused to take action for the mistake and damage they did to my dog yet alone the trauma they put him through!! I sent all pictures etc to the owner as proof and we were ignored yet again !
