Bad Customer service

I purchased my Samsung S6 Edge two months ago.<br> It started over heating and loses network i can't use my phone at all.<br> Last week my phone got booked at Samsung store in Morningside they kept it for three days and it was returned to me on Friday. A few hours when i got it back it started overheating again same problems again. Took it back and it was returned to me again on Saturday the 28th and its still not working<br> Samsung you truly have wasted my time. I use my phone everyday its my life i regret buying it with such bad service i should have taken iphone 6 at least apple store rectify their mistakes and own up to them.<br> I truly cant and no longer hv the time to keep driving around and still get my phone back with it still not working. Today is the 29th still the same issues.<br> I am truly an unhappy customer.
