SPCA in Witkoppen ****ed my cat and her 4 kittens!

I took my Cat and her kittens to the SPCA in Witkoppen is been 3 weeks now. I called in today to ask how she is doing with her kittens. I have been told she carried a disease called which was uncurable and they have put her and her 4 kittens to sleep(Meaning ****ed them). I wasn't even informed what so ever! I understand I had not vaccinated her when I took her to the SPCA or at an early age of her life cycle but I personally believe I deserve to have been informed about her sickness and before they had decided to put her to 'sleep' with her kittens. It was hard enough to take them there yet I had to call them myself just to be told they ****ed my cat and her kittens!
