Car salemen

Long story short I went to the car dealership last week to help with the finance company they set me up with and to just see what my option were to trade in for a Jeep. Took me over an hour to leave because they kept sending different people to “convince” me the great deal I’d be getting if I buy a 2019 Nissan rouge right there right now 🙄. I don’t like SUVs and I definitely don’t like silver which was the only color they had plus I wasn’t planning on buying a new vehicle all spontaneous like that. They called me all weekend and are still calling me. I told them I was not buying anything right now but I guess they’re not getting the point. Is it rude if I just ignore all their calls and texts since they’re not listening to me? I hate being mean or rude but they’re working my last nerve
