Intellectual property theft

My Name is Katleho Seduku. I'm writing this review on terms that I had sent Chekers my proposal for the same app they are calling Sixty60 back in 2017 with an proposal that i have an idea that will boost the client base of supermarkets in South Africa. My proposal was viewed by chekers on Facebook and I was told to visit the business to business portal on their website. Bear in my my proposal back in 2017 looks exactly the same as what they have today the only difference is the name of the app but besides that all the details as per their app is exactly the same as what I proposed to them. When I saw this app I tried sending them an email will all my screenshots showing I had sended them this 4years before they even thought of making this app and was not even contacted regarding this. I have full prove of what I am showing you guys and you can also look at my tick tok video exposing how we are being ****** of our intellectual property. I am 31 years old and have a daughter, when I had this idea I thought I would leave a legacy for my daughter not knowing that big companies such as Checkers takes people's idea an make huge profits out of them without even compensating the person who actually came up with an idea. How will we grow as a nation if innovations an ideas are being ****** from the poor. So if you want to view the vid check me on tick tok Katleho Seduku and view the exact same app idea which was proposed to Checkers 4 years before they actually made the sixty60 app.
