I got boned by riot.

Hi, I have been playing since season 4 on the same account, always played to have fun, never really put a lot effort into ranked up until very recently. I had made it all the way to gold 1. stopped playing for a bit and ended up in gold 5. I started my promo games there. I was 6-3 until while in my last game, 4 out of the 10 players in the game DC. 3 of which were on my team. We lost...... After that I checked my stats because i was sure riot would give me a loss prevented.... They didnt. Still somewhat content with 6-4. I logged out and logged back in to see my standing. PLACED IN SILVER 4?? riot.. Please fix your shit. You have made an incredible game no doubt. But this... this is sad and makes you guys look like a huge group of fucks. Majority of games i play in ranked I do very well. I more than deserve to be in gold. Plat im even told. For fucks sake open your eyes and FIx It. not that hard. Thanks
