Despite having the correct information in my father's file, the cemetery had drafted a service order that downgraded the quality of vault that had been prepaid and billed us for opening and closing the grave, which had also been prepaid. When we produced our copy of the agreement and challenged their service order, they cheerfully corrected the mistake and delivered very good service. However, sloppiness is the best possible interpretation of what happened. More likely, they try to make some extra money on prepaid contracts all the time, and that's taking advantage of people when they are most vulnerable.
Pros: Responsive once they knew we knew what we had paid for
Cons: Attempted to downgrade, double charge prepaid services
