Lost Navigation software - Poor service delivery from Ford Alberton

My husband's Ford Ranger Wildtrak went in for a service in December 2021, at the same time we asked that the Navigation system get's updated as we saw on the Ford website that there is an update on the Sync 3 available but we've been getting error messages whilst trying to do the update. We were charged quite an amount to get this done. When my husband collected the car, the first thing he noticed as he got in is that the navigation function is no longer there (as he always drives with the navigation displaying). He went back in to discuss this with the service manager. It's now 2 months of going backwards and forwards, us constantly phoning Ford and following up with Ford on the next step on how to get this resolved, the vehicle was back at the dealership for a few days and all we get back from the branch is that they are unable to get it back as it wasn't supposed to be there in the first place. How can we buy a vehicle from a Ford Branch, after their inspection on the car, the salesman focusing our attention on this functionality as it was a minimal requirement for us and now all of the sudden it's not supposed to be in the Ford Ranger Wildtrak!! We've escalated this problem to the Dealer principle, who comes to a meeting ill prepared, my husband needing to tell him what the problem is, and he has no solution, taking zero ownership of the problem. We escalated this to the Ford Customer Care centre and nothing gets done, we just get called to see what we managed to get done between the dealerships! We need to now wait for a courtesy car to become available at the branch that we bought the car, for them to now have a look to see if they can rectify this mess. Ford fix the problem! Stop looking for excuses to cover your mess! We need solutions not excuses!!!
