forza 7 freezes

hi purchased forza 7 ultimate 2 weeks before official launch , for the last 2 weeks the game freezes when trying to load a race ,it freezes at pre race , just does not want to load , and after a few minutes it sends you back to the start screen , this is on xbox one slim , paid $140 for this game and so far its a dud , have forza 4,5,6 and horizon 2 and 3 and they are all fine , contacted microsoft last night via online chat and they said there is a problem with the game and the servers were going to issue a patch , well no patch been done as yet , really peed of with forza 7 you would think with all the hype going on the last month about it that they would have got it right , its not just the downloaded version its the disk game as well , i have gold membership with xbox and this game is unplayable for the last week or 2 , you cannot even go into free play as it wants you to continue where you are , if its not fixed in the next week i am going to request a refund from microsoft as the game is a dud , i have been listed with microsoft my acct as being some one who can not play the game due to it freezing , so damm frustrating , so many complaints according to microsoft , whats the point of paying $140 and you cant play the damm thing
