Where is the website for doctors to make complaints about patients?

Medicine — as we are all aware — is an art, and it is the human connection between doctor and patient that is the backbone of the therapeutic alliance.
Most doctors are decent human beings who want to achieve the best outcomes for the patient in front of them.
Most patients are equally honest, decent human beings who treat their doctors with respect and who genuinely want to get better from whatever affliction is affecting them.
And then there are those who deceive.
