From the pics you showed me, there was definately SOMETHING wrong with those rats, more than likely mites. Sounds like she's just feeling bad about giveing you the money back. She needs to though and it sounds like those rats that are in the petshop need treatment.
I would explain to her that you could take this matter to a lawyer, I don't know any other laws other than American but if a place of business gives you a refund they can't ask for it back. It's her fault she gave you the refund and in my opinion you deserved it. There is no legal standing for her to have the money or the rats, you payed for them she chose to gave you the money for their vet bills. No legal standing on her part to get that back.
But you seem to have harrassment happening, a lady with sick animals owning a pet shop and lots of stuff happening. I would call whoever deals with animal cruelty over there and get them on top of things with that lady. She really needs to get those rats to the vet and get their mite treatment, or even just look up the proper doseage for revolution and write off a few containers of that D: That's just really crappy treating those poor animals like that.
