So Almost 4 months later we got our turtle back.. The vet had him for this long because they couldn't figure out a quick way of making his so called "shell rot" go away. He seems to be doing better now, but he still has scars from the rot on his shell which the vet believes will remain for ever now. But thats ok.. we have him back and that's whats most important. He is clearly more active and less scared of us now.
We are happy

Thanks to all you guys for the advice.. We were persistent and we got him back..
