ServiceNPC will continue to appear after canceling service

So I had a rancher on my lot and decided to get rid of them along with expense. I went through the process of firing them by clicking and interacting with them. Even dismissed the service through the phone. They wouldn't leave the lot. I also tried to reset them, nothing changed. They still remained on my lot doing things around the area and taking household funds. Well, I decided to just delete the sim altogether since nothing was working. Shortly afterwards a brand new rancher comes onto the lot and starts doing the same thing, I went through the whole process once again and nothing changed, then I ended up having two ranchers on the lot at the same time. They also don't leave the lot at their scheduled times, they almost resemble having a butler being on the lot 24/7 without needing a bed. You can only assume my frustrations as it's depleting me of my household funds left and right and I don't even require the service. I would love if someone could look into this issue please and to know if anyone else is dealing with this issue.
