Samsung Galaxy Core 2 charging problem and a weird problem.

Hello, I bought a Samsung Galaxy Core 2 this month and after 2 weeks, a problem appeared. When I tried to charge my Galaxy Core 2, it didn't made any indication that its charging or not so I made it stay like that but after sometime I came back saw the battery level rising but still no indication that its charging or not and now I cant live that!! So I switched off the phone and put it in charger but then, the phone switched on automatically!! And I saw that sometimes, (yes sometimes) the indication appears!! So I tested it by putting the charger off and on again so the results are same....NO INDICATION!! But if I put the phone off and keep it in charge it turns on itself. HELP ME PLEASE!!!
Rooted or not rooted? :- Not rooted
Stock or custom ROM? :- Completely Stock
Was the phone ever went wet? :- Never! I cared it a lot
Now please help me!!!
