Banned for "throwing."

Hey guys! Ive recently came back to this game, and well I suck. I hopped in ranked and a lot of people said I was throwing, and called me some slurs. I try every match. Even in quick play. They call me buns. And now my account has been suspended! Has anyone else gone through this?

I tried to stay in the quick match towards the end though. Is this normal? Or do I just really suck? Console too.
