By any chance is this a PetSmart? If so you can also contact the local animal control. They have to get quartlerly inspections in order to keep the license to sell animals valid. All animals must be in good care/health/clean environment. Chances are they are not due for the inspection or already had it. Could help your case a bit. Filing with corproate doesn't usually amount to much because in the end all of the animals are just numbers and price tags to them. Good luck with everything. This little guy really needs you.
