Shameful service and poor treatment of customers

I bought a for my daughter a previous tab beginning of July 2023 at ackermans. Unfortunately while playing , a friend stepped on it and the screen stopped working. As a customer I went to the store to get it fixed, taking all cost liability. The store told me that they won't fix it because it was my fault, however I can't find the screen anywhere since it's a new model. I feel unfairly treated by the store because I am a customer whose willing to pay. Why are they selling the product if they are not willing to fix it. Very poor and unprofessional treatment , I won't be buying from them again
