Repair to my Samsung Note 4

On the 28th December 2014 I took a contract with Vodacom with a Samsung Note 4. The Samsung Rep in the store gave me a demonstration as to how the Note 4 is one of the best devices on the market. And particularly because I work within a Public Service environment how this device could enhance my personal and official quality of life .In less than two(2) months the phone had problems with network reception, dropping calls/cutting calls, data services, son the 24th Feb 2015 the phone was booked at Vodacom Repair Centre Pietermaritzburg. The phone was returned to me in March 2015. Vodacom undertook major repairs to the device replacing the A/S REWORK KIT, ASSY PBA MAIN - N910, and ASSY CAMERA MOD 16M-N910(which I never asked).The device continued to give problems I took it to the authorised Samsung Repair Centre in Pietermaritzburg on the 1st April 2014. The consultant said that the repairs undertaken by Vodacom is questionable, that they can only assure me of their workmanship. So the unit was sent for repairs for the second time. And Samsung then replaced the MAIN PBA , SUB PBA FPCB and REWORK KIT. of which Vodacom had already done. My phone is still with Samsung
