Got Blocked from CS:GO Matches for Two Days at Valve

For the past two days, I've been unable to join competitive matches in CS:GO. My brother suggested boosting my rank (double Keles), and he played a game in Silver 1, reaching 27 kills and 4 deaths. Yesterday, when I tried to play a competitive match with a friend, he couldn't join because my trust factor was low; he sent a screenshot as proof. After some research, I learned that receiving compliments could boost it, so I used a bot to get commendations. I added my friend, had him check my CS files, even had him write on my profile, but I still can't find a competitive match. What should I do?
