NO HELP AT ALL. VERY FRUSTRATING

I bought my Samsung S6 on the 20th of May 2015.This phone started giving me endless problems before it even reached 2months. Took it to Samsung for repairs but they couldn't assist because they don't the Vodacom protector code, so I then took it to Vodacom in Gateway, they booked it in nd I was fone less for 7-8 days, they brought the fone back and it's still giving me the same problems. Today I went back to Samsung still I wasn't assisted then went back where I had purchased the fone at Pine crest and still not being assisted. I'm paying a lot of money for this fone every month, I've wasted so much of my time and petrol going up and down for a whole month and I'm not being assisted, from the 16th of July I'm up and down they not helping. I want them to give me a new fone because its pointless to have this fone for the next 21 months if it's gone give me problems so soon, how many times will I be repairing this fone, I can afford to use more money on somethings that's not of use to me
