Charger type C and battery charging issue

I got a Blackberry Motion... everything very nice.

The phone came with his charger... a black one.

My question is that the plugin type c cable... doesn't fully enters in the charging hole. But it clicks a little bit. I saw all other phones that their chargers enter perfectly and they stay very tight in there. And beside this, after 1 year of use... i'm starting to see that sometimes... it chargers but exits the boost mode, and i have to reactivate it and sometimes... and it doesn't quick charge even if boost mode is on.

Maybe the charger dies? Or there are some battery problems? And where do i get a charger original and to fully enter the charging hole?
