Late utilities transfer

[Amy Lee]

I was being naive and let the tenants move in without having utilities to their name. I outlined this in the ad but nothing in the lease. At this point, I'll be paying for their utilities for 1-2 weeks. I can't make calls to the companies with the weekend and holiday. Do I have to eat the cost on this? Is there a way to throw this back to have them pay? How would I figure what amount they are due for?
