Give me rewards back plz

Hi, my name is adrian, my summoner on NA is thelastcuban. A month or 2 back i got banned due to toxicity. Although i do not agree with the ban i recieved, i did not complain because i know league knows what they are doing with their game. The ban i believe was unfair. I was "toxic" that game when an enemy player called me garbage bc i died to them. I proceeded to kill them and called them garbage because of my seeking in revenge. After that game i got banned 2 weeks for that. I took the ban, but for some reason i lost all my rewards. And i guess i can understand that for a couple of weeks but i have been a lot less toxic, if any, and believe that i should be awareded my rewards again please.Thank you for your time and concideration
