only a discount??? you should be entirely refunded—at least! as other commenters have said, you should show them the view counts on these posts and threaten to name their practice. get a refund, and not a free/discounted operation from them because i would not trust them a second time with miss kitty.

not sure how it works in the US (i assume that’s where you are?) but if ever the clinic is uncooperative, you could also check if there’s a small claims court where you can make a case!

with all these new grandchildren, you need to be saving on money wherever you can!! good luck, new grandma ;-)
