EVERY breeder or anyone else with a reputable reputation that I personally know has a quarantine period -- if not for the sake of letting their new acquirement settle in, adjust, and to ensure that it's alright, but also to ensure that, in the case you bring in a sick animal, that you do not infest the rest of your collection with god-knows-what.
The people that sell these animal have EVERY right to inquire after your husbandry -- and it seems to me, due to lack of certain responses and photos, that you may now be second guessing your own. I wouldn't hesitate to post pictures of my animals, especially in a case like this, because I know that I do what I can to ensure their optimal health and husbandry. It seems to me that you do not, which is why you will get nowhere with this.
1) You have not posted the pictures, as requested
2) You denied hospitalization for the animal based on already spending too much on it. It shouldn't matter how much you already spent -- it should matter about getting it healthy. And you state that you are treating it - but if you did not know how to properly quarantine, I highly doubt that you know how to properly treat an RI, nevermind with what to treat with.
3) You continue to state that you don't care how your reputation looks -- but you really should if you are in this for more than a hobby. That you don't care says a lot about a person.
And a few tips about your website -- if you want to look reputable and professional, stating who you will or will not buy from on the first page is not only tacky, but very un-proffesional.
But a spell checker and HTML validation is. Maybe even an editor to pick up on grammar (or lack thereof). If you want to be a professional, you need to act it. And in order to act professional, you need to BE professional which you, young sir, definitely have a long way to go to achieve. You will not be taken seriously until you take yourself and others seriously. Until then, you're just another joke, unfortunately. YOU need to prove that you are reputable to other people, but by simply telling them that you are is way off the mark. You need to SHOW them, and a good way to start is by showing that this animal you have really is ill -- otherwise it's just a comment from someone who doesn't seem to know what he's doing....
