Inevitably lost D3 promos because of a win not registered.

Yesterday i was in my promotions to D3, I won the first game and then played the second. I won that one too but the stats didn't show. Waited five minutes but still nothing, so i skipped and didnt think much of it. However it didnt say i was promoted in my profile "Diamond IV 100lp" so the next morning i checked and still the same thing. Only 1-0 in my promos. Later today played two more and lost cuz of wonderful feeders and unlucky matchmaking. I checked my match history and saw that the game that won my promos didn't even get and ip for the win. Hence it truly never got registered as a win. Yea the reset is in two days, but coming from a 6 year dedicated league player who grinds ranked, this really frustrates me. I hope whatever caused this gets fixed, cuz i know riot "cant do anything about wins not registered"
