I need help for my dog's cremation

I'm ashamed to ask for help, but after a last couple of rough month paying vet fees and medication for my almost 14 years old dog, Csöpi, who had mammal cancer, my bank account is completely empty and I still have almost 600€ to pay for the cremation and the urn to bring her home.

I can provide the bill I got from the crematorium, but briefly: 

Cremation: 300€ 

Collection fee: 58€

Urn: 92€

Paw print: 20€

All together including tax: 570€

They refused tot me pay in 2 part, which I could still manage somehow, but in one amount, I have no chance to pay it.
