Heart broken

I made the gross mistake of taking my cat to this hospital on a Sunday, she had cystitis which was nothing serious at the time! After assuring us that they had checked her kidneys and that they were fine they gave her an incredibly high dose of metacam which if they had done proper diagnostics on her kidneys would never have given her, she deteriorated over night and so we took her back to them for a follow up a few days later, again instead of doing proper diagnostics they told us she was fine and gave us a paste to increase her appetite !?!? If they did their job they would have seen her kidney levels were through the roof!! We tried everything to get her well again and I spent over 10K on her in and out of my local vets hospital, I lost my beautiful Ming on Monday this week she just never came back from those meds! I want the world to know what happened to my cat because of these people, please don't take your animals here not ever, I wish I could go back in time! I've heard so many terrible stories about this vet and I feel like not enough people know! I can't bring her back but I can try to let everyone know what happened in the hope that this does not happen again!
