Laying a complain

I bought an Olive oil India Henna hair dye from clicks on the 30/11/2019 and used it the very same day. The following day I woke up having blisters on my sculp. On Monday morning I woke up with head swollen, then later that day I went to see my doctor and he was shocked with how I look. He gave medication but I woke up with my condition worsened the next morning. I went back to my doctor then he decided to transfer me to hospital. I was admitted for four days in hospital. I have used dye before but I never experienced such trauma.The day I was discharged from hospital I decided to check the expiry date and the product had expired for months but it was kept on the shelves. The product had expired on the 01/08/2019.
