Mr Price thieving behavior

Bought a mobicell tablet from this store it never ever worked since day one. I tried to return it at a different store to the one i purchased they refused take it and said i have to go to the shop i purchased it from which i tried to explain tonat least three mr price branches that i was not able to do that because we had to be in a different province for a family emergency. None of them would help me. At a later stage we returned to jhb and i took it into the branch i purchased it from. Greenstone. They said they can only repair it. I handed it in and had to wait almost 6 weeks for the repairs and had no updates on its progress unless i went to the store to check myself. When we received it back they saif the entire processor needed tp be replaced which is the entire device itself tp my understanding. The tablet worked in store. When i took it home and turned it on it worked for approximately 30min and then the screen went white with black lines across it. I tool it back asap nd explained the issues we could hear it but no screen display. They took it back and wr continued to wait another month with no communication as usual unless i went to check on it and was told that parts are being ordered they might not have used brand new processor so maybe that was the reason for the long wait again. I was patient and cautiously waiting ... until i received a call today 15/5/2019 at 11:42 saying mr price will not fix the tablet because the lcd is cracked all of a sudden with it being in their possession for over a month explaining to me the wait was for parts now they want to blame us for break the lcd in the space of 30min. This is unacceptable i asked for the regional manager to call me i am still waiting.
