DON'T VISIT PET PLANET

Pet planet (under rufi in gulistan e johar) killed two of my stray cats, the first one was a stray cat I have three cats in home so I cannot have more that's why I help stray cats outside my home I gave him food and water everyday he was healthy but suddenly he got fleas it was only 2 to 3 days since it had fleas and he was not that bad to die but when I took him to pet planet he was a kitten and Idk he gave him how many injections and later next day he died. I wasnt sure it was pet planets fault so I didn't reacted much to them but after 4 to 5 months another ginger kitten I took to them had flu for 1 week I took him to vet they once again gave him 3 injections and drip he was a little kitten and what happened yesterday he also died just 1 day after I took him to pet planet before it he was okay he even roamed around but after I took him to pet planet he was only collapsing everywhere and just after 3 to 4 hours I found him dead near my home. I asked one of my personal vets in Hyderabad he said how can he give him 3 injections and he didn't even gave him oxygen mask that was needed as he had flu and he has difficult in breathing. Today I inspected and I think the reason he didn't gave him oxygen mask is that they didn't had one and the vet didn't told me that he needed one if he would had told me in would had taken him to companian but he didn't and gave him unnecessary injections. As a 14 year old idk what I have to do. Just wanted all of you guys my experience. Thanks for reading!
