Dc in placement

Hi, so Idk if there's another place for this but I dcd during two placement matches for season 5. After this first dc I thought i had fixed the problem but apparently I did not. This is very frustrating to me because I had finally reached gold V and now Im guessing I will drop pretty far once I finish my placements. So I am posting this in the hopes that someone can pull off a miracle for me. Also, I do not have a history of leaving matches neither in the game nor the queue. It simply is not something I do.
