Has anyone ever refused a route?

I came for my block and when I scanned the assigned one, there were way too many packages and very far from the station towards an areas with extremely high traffic. I’ve never gotten a route with a such a high number of packages that is so far and with many apartments! I honestly freaked and I called support to return. It’s the first time I do it and I’m in great standing but I’m scared about my account. The guy at the warehouse said I had to do it and that it would affect my standing, but honestly I was not willing to do it. It was very far, at a highly trafficked area with a lot of apartments. I was never going to finish it on time. Help, what do you guys have to say?
