Okay everyone, get this.
Just spoke to the vets re getting them to send a letter to the insurance company. They said no.
At the time, they said that a particular tooth had caused the abcsess, and so they removed it. That's all I knew, as we picked Manoon up after the operation and didnt hear any more. Now that I've made this enquiry, the vet now says that the tooth WASN'T infected after all they found, once they'd removed it, and therefore it didnt cause the abcsess. They still removed the tooth BECAUSE of the abscess, in my opinion that it apparently didnt turn out to be the cause is neither here nor there surely
The vet said their position is the tooth had to have been the cause of the abcsess in order for me to be able to claim the whole costs as one treatment, and therefore it would be a fraudulent claim if they wrote otherwise.
SO I'm 50 squid out of pocket due to a technicality
I'm not impressed with the vet at all.
