Samsung S8.Same problem

I have just got my Samsung S8 phone back from repairs, after I have send it in for a second time for repairs.Bought times was for the same problem. I even phoned them and told them what the problem was.Wanted to speak to the Manager but he was on leave,so I spoke the second in command.I told him that it was in for repairs before and they have send it back to me and said that it was fixed,but to my suprice the same problem accure and it was even worse. He promised me that he wil lookin to it himself.I got a message fromhim that the phone is fixed and is on its way to my nearest Vodashop. I got to the shop but they said on a letter NFF (no fault found)but the shop tested the phone an said to me that They are very sorry but they have to send my phone back again to repairs because that it is stil not charging. This is now the third time that I have to send my phone back to Vodacom for repairs and that all on the same problem. Well welcome to VODACOM,there servise is up to ......... same as there signal.
