Ubisoft is the worst company I have ever bought something from.
They will never read this or care but they have given me the worst game experience ever. I bought Rainbow Six : Siege because I enjoyed Vegas 2, and I do enjoy the game ... if the servers would connect me every two years and didn't take a lifetime to load one person in the game. The worst thing was when I was playing ranked on this game it disconnected me, de-ranked me and gave me a ban for 15 mins.
I would file a complaint but their support is trash, and the people I talked with were unfriendly. Tried to change my username once and it said everything was considered "vulgar". To change my name I had to contact customer support and have them do it manually.
