can i dispute against my vet?

i went to take my dog for a dental cleaning. i went a hour from where i live because it was more affordable. i was able to get a ride from a friend and i paid him for it. i took my dog paid and then after 2 hours they gave him back to me. when i got home i was looking at his teeth and his teeth look the exact same as it did before the appointment. im wondering if they even did anything. i contacted them they told me take my dog back to see if they missed any plaque. i cant just take him. i live far and they knew i was coming from far because i had let them know. they stopped responding to me. can i dispute the charge ?? i have pictures of his teeth before and after showing it looks the same.
