Faulty phone that just won't come write

Hi.I have a big problem with my Samsung S5 which just won't come to work as it should after going to repairs for the fifth time.I am tierd of sending it for repairs five time for mostly the same fault is ridiculous <br> My phone heats up and the battery drains out very quick.It has a new charge port fitted /a new battery fitted /new board fitted but same problem after a few days every time<br> The sad part is that ever time I send it I suffer down time without a phone and it costs me R150 to take my phone to the repair centre.which I am not compensated for<br> But placing on record that the staff at the Smart care centre are mostly helpful and understanding for the most part.<br> But that doesn't help one bit if my problem is not sorted .it is mind blowing to even try to understand that a huge company such as Samsung can't meet the needs of the very people that keep them in business .<br> I am very very disappointed in this whole episode of my phone because I have always been a proud Samsung user for the most of my life.which now is starting to put second thoughts in my head.<br> I really would not like for my phone to be repaired any more times .please charge me a diff and replace the phone.or change it.
