Shocking, unprofessional behaviour

I called them about my kitten Binky, who has an eye problem in one eye. My local vet was not sure what caused it, and Binky also has juvenile gingivitis, so I was worried. On the phone their receptionist said it could be FIP, which is a deadly virus, and this obviously made me completely panic-stricken. I then made an appointment the following week with their cat specialist to assess the kitten. When I called again prior to this appointment to ask a question I was told I was not welcome at their practice. This was extremely surprising, confusing and upsetting. I had an appointment and then they just cancelled it, after telling me my kitten possibly has a deadly condition. They said they refused to see me due to me missing an appointment 15 months before - for my other cat Zorro, who ended up having recurring pancreatitis and had to be put to sleep. The ordeal with Zorro was extremely harrowing for me, he was my companion of 18 years. I missed the appointment because I had a stomach bug that day and was too sick, which I did convey at the time. They said they had spoken to my partner at the time, I don't even know why they would have his number. I was very confused by all this and offered to pay for the missed appointment but they still refused to honour the appointment we had made for the following week.

I was never rude to anyone at this practice and I find it cruel and careless that their receptionist told me that my kitten might have a deadly disease, and then they cancelled my booking based on events 15 months ago. Apparently it was Dr Miller himself who told them that his practice refused to treat my kitten, but I have never even met Dr Miller nor have I even spoken to him.

Surely it is not ok or professional for a receptionist to be offering diagnoses on the phone and then for the vet to refuse to treat a very serious disease with no proper justification?

There was no proper justification or reason given for this vet refusing to treat my kitten as I have never been rude to anyone at this vet and offered to settle the amount for the outstanding consult, despite being too sick to attend at the time.

These people seem more concerned about their own egos and taking umbrage for fictitious offences than about the animals who are suffering.

In my view their behaviour is a violation of the SAVC code of conduct, which states that: "A good veterinarian makes an uncompromising commitment to sound professional, moral and ethical practice, based on dedication to the health and welfare of animals". I also believe the receptionist behaved in violation of section 3.5 of the SAVC code of conduct on "TELEPHONIC/VERBAL ADVICE TO CLIENTS", she is not a vet and was telling me that my kitten possibly had FIP, then this practice refused treatment.
