Qaulity of repair

Vodacom customer care in vodaworld service is great . so please don't misunderstand my complaint. I have a Samsung note 4 and it is less than two months old, my phone has already had a mother board replacement when I received the phone back I noticed the screen was lifting and the housing was also damaged . I also encountered the wifi and Bluetooth to be problematic aswell as the finger print reader was faulty, the phone was then booked in once again and the housing and screen was replaced but the finger print reader is still faulty I had too once again book it in because the quality of repair was pathetic .I am unhappy as I am paying R999.00 pm and I have no joy regarding my note 4 . Vodacom should be checking the quality of repair and deliver all their services as the so called best network
