Just a note re the initial call out fee.

When we do a service call, the invoice always goes to the party who requests the service call. We would not change the invoicee on work order unless that new invoicee notifies us in writing that they will accept the invoice instead. You can understand the issues that might arise from an initial customer simply saying "Those guys should be paying this bill instead". As the service provider it's not really my reponsibility to figure out whether it's strata or owner who pays the bill.

In your case, I know it's not a large amount, but to protect yourself from any potential creditors or legal issues you might want to pay yourself, and then pursue compensation from your strata. Otherwise, you really need to have them notify the plumbing company they should be the invoicee.
