teacup puppy botique store

his place sold me a sick puppy. I bought a puppy yesterday and I just took her to vet because she wasn't moving. I was told she was minutes away from dying. And the store isn't covering the vet bills. I bought her for $8500 and now have to pay a vet bill of $543. The vet said its a pre existing condition that made her have a hypoglycemic episode. The store told me its my fault because I didn't force feed her. It's not normal for a dog to not wanna eat and me to have to force feed her. And even with force feeding she still had a hypoglycemic episode. I grew up with a teacup puppy so I know how to take care of one. The vet told me I bought a lemon and told me to see if I could get a refund since it's been less than 24 hours. So I am stuck paying for a sick puppy that they sold. Save yourself the stress, I wish I had read reviews of this store before buying a puppy. They do a great job of making you think they're trustworthy. Before the dog left their facility the store associate took the puppy and said the vet in the back just said she was very healthy and ready for adoption. Come to find out they don't have a vet in their store on weekends and I bought her on Saturday. I was lied to. When I told the store owner this she called me a liar. This is no way to treat someone who just gave you $8500.
