Grooming by Terran

I dropped my dog off to Terran at noon and after not hearing from her at 4:00pm I texted her and she said her clippers had died so she had to go to petsmart in Draper to get a new part, I did not get my dog back until 7:30pm and when she handed him to me she said she was sorry that she had clipped him and had put some sort of liquid band aid on it, I didn't feel comfortable there so I just left. After I got him home we looked closer and his wound was very bad, took him to the veterinarian and our dog ended up having to have surgery because she had clipped him all the way to the muscle. I have tried contacting her more than once about this but she is avoiding me. I just want to warn others because I don't want this to happen to anyone else's dog.
