I assume you're exaggerating the numbers because that would mean the final score in the game was 3-49, which I highly doubt.
In fact, out of your last 15 ranked games, you have only won 3. There is no way you were recently in a promotion series on this account.
You have never played Darius in ranked, only two ascension games, again on this account.
Furthermore, all of your games on this account have single digit (usually 3 or less) kills and double digit deaths except for a handful. There are multiple games that you have had over 20 deaths. There are some games it appears you left or afked partway through.
If you're going to try and post lies to try and get sympathy from others, at least post believable ones based on an actual game you've played. Alternatively, sign into your main account (which I wouldn't be surprised to find permabanned for either trolling or intentionally feeding).
