how to convert raw sql subquery to linq query

i have this query and i am unable to convert it to an equivalent linq query

select distinct  u.Name,p.PName,u.AccCreateDate,up.BuyDate,u.ID from Users u

inner join UserPackages up on up.U_ID=u.ID 
inner join Packages p on p.PID=up.P_ID 

where u.UserRef_No in
(select  RefOf from Refers r inner join 
Users u on r.RefNo=u.UserRef_No inner join UserPackages up on up.U_ID=u.ID where up.PackageStatus=1 )

i tried this but it doens't work

 var referrals = (from u in dbs.Users
                                  join up in dbs.UserPackages on u.ID equals up.U_ID
                                  join p in dbs.Packages on up.P_ID equals p.PID
                                 where u.UserRef_No.Contains
                                (
                                  from rr in dbs.Refers
                                   join uu in dbs.Users on rr.RefNo
                                     equals uu.UserRef_No
                                   join upp in dbs.UserPackages on
                                    uu.ID equals upp.U_ID
                                   where upp.PackageStatus.Equals(1)
                                   select rr.RefOf)
                                 select new UsersHavingReferrals
                                 {
                                     Id = u.ID,
                                     UserName = u.Name,
                                     PackageName = p.PName,
                                     AccCreateDate = u.AccCreateDate,
                                     PackageBuyDate = up.BuyDate

                                 }).Distinct().ToList();
