So Angry and Frustrated!

For the past two years I've been searching for a good vet for my dog. She has a bump on her right eyelid and it's getting really big. So far the vet's I have taken her to have been rude and accuse me of not taking care of my dog. The last vet wanted to pop the bump without any pain medication. When I told the vet that I wasn't going to let him do that without any pain relief he tells me if my dog goes blind it will be my fault. He then goes to tell me how upset he gets when dog owners don't take care of their dogs. I stormed out of there and the search was on again for a good vet.
Well Friday I took her to a very recommended vet. The reviews were nothing but praise. I took her in and they were as nice and understanding as can be. I was so happy. The vet decided the bump had to be removed, even though it doesn't seem to bother my poor doggie. So I made the appointment for the surgery. They gave us instructions for pre-op, no food after 9pm and to drop her off between 7:30am and 8:30am. We let them know that my daughter had a dr's appointment at 4pm and they told us no problem that we can pick up Heidi(dog) at 2:30. We made sure to tell them twice so they wouldn't forget. Well 1:30 came around and no phone call from the vet. I gave them a call and the vet tells me she was really behind and she hasn't gotten to Heidi yet. I reminded her about my daughters appointment and she tells me she didn't know about it but that Heidi was next and I can bring her home at 5:30. She also told me I can leave her overnight if I had too. I told her Heidi is a pound baby and I did not want to do that to her. I went to pick her up at 5:30 and to my horror they hadn't done the surgery because they said I told them I will pick her up in the morning. What! So I told them to forget the whole thing I'm taking my dog home. The vet takes me to the back and there's my poor Heidi knocked out because they were just going to begin the surgery. I told them I'll wait for her to wake up but I'm taking her home.
My poor Heidi was locked up all day with no food and probably wondering what she did wrong. After I got her home she was a nervous wreck and even now she walks by me with caution. She seems so scared now. I'm sure if that were their dog they would not be happy. They traumatized my dog and I'm sitting here crying because my once happy, bouncing dog is now so sad and scared. I hope this will pass with time but for now I have to do my best to keep her as comfortable as possible.
