Bank Loan Case Study Rejected twice

My project is rejected twice due to plagiarism. I did it the second time changing everything by my own. Still it says i have copied from the last two links they have provided. I changed my presentation slides and descriptions. It will be very helpful if i get detailed remark of what i should change now?? Should i perform all the excel tasks in a differnt way? please guide me that what changes i should make to get it approved?
