Huge invasion of privacy and breach of confidentiality by Blinkit

I am utterly shocked and furious at Blinkit. Delivering my highly confidential documents- handled days ago-to a random person today is beyond negligence. This is a blatant invasion of privacy, a major confidentiality breach, and a huge disservice to customer trust.

Yeah i understand that I should've used better judgement on my part and taken the print in person but i went with blinkit because I trusted them to keep their word on confidentiality and they even say they delete files from their cloud once they print it.

I am so pressed about this because some of these documents contains pan cards, home addresses, bonds and even my medical license, which in the wrong hands is a dangerous instrument let alone a random person who received it by chance. thinking of handling this legally.

What can I do legally about this?

Thankfully a kind soul recognised the sensitive nature of the documents and travelled all the way from their home to return the documents to me even though he received the wrong ones for his order and didn't ask for any of this.
